Before winter sets in is a good time to check your cabin air filter, after it’s been working hard all spring, summer and fall. Cabin air filters clean the incoming air and remove allergens, and according to the Car Care Council, should be replaced every 12,000 to 15,000 miles, or per the owner’s manual.
The cabin air filter helps trap pollen, bacteria, dust and exhaust gases that may find their way into a vehicle’s air conditioning and heating and ventilation systems. The filter also prevents leaves, bugs and other debris from entering the heating, ventilating and air-conditioning (HVAC) system.
A dirty or clogged cabin air filter can cause musty odors in the vehicle and cause contaminants to become so concentrated in the cabin that passengers actually breathe in more fumes and particles when riding in the car compared to walking down the street. A restricted cabin air filter can also impair airflow in the HVAC system, possibly causing interior heating and cooling problems, important for staying comfortable this winter. Over time, the heater and air conditioner may also become damaged by corrosion.
Most filters are accessible through an access panel in the HVAC housing, which may be under the hood or in the interior of the car. An automotive service technician can help locate the cabin filter and replace it according to the vehicle’s owner manual. Some filters require basic hand tools to remove and install the replacement filter; others just require your hands. Filters should not be cleaned and reinstalled; instead, they should be replaced.
“Many people don’t even know they have a cabin air filter in their vehicle and most others aren’t aware of the health benefits of changing it,” said Rich White, executive director, Car Care Council. “Checking the cabin air filter is a simple preventive maintenance step that goes a long way toward protecting passengers, as well as the vehicle’s HVAC system.”
During Brake Safety Awareness Month in August, the Car Care Council reminds motorists that routine brake inspections are essential to safe driving and maintaining your vehicle.
“When it comes to vehicle safety, the brake system is at the top of the list, so have your brakes checked by an auto service professional at least once a year,” said Rich White, executive director, Car Care Council. “Knowing the key warning signs that your brakes may need maintenance will go a long way toward keeping you and others safe on the road.”
The Car Care Council recommends that motorists watch for seven signs that their brakes need to be inspected:
- Noise: screeching, grinding or clicking noises when applying the brakes.
- Pulling: vehicle pulls to one side while braking.
- Low Pedal:brake pedal nearly touches the floor before engaging.
- Hard Pedal: must apply extreme pressure to the pedal before brakes engage.
- Grabbing: brakes grab at the slightest touch to the pedal.
- Vibration: brake pedal vibrates or pulses, even under normal braking conditions.
- Light: brake light is illuminated on your vehicle’s dashboard.
Brakes are a normal wear item on any vehicle and they will eventually need to be replaced. Factors that can affect brake wear include driving habits, operating conditions, vehicle type and the quality of the brake lining material.
Using the Car Care Council’s free personalized schedule and email reminder service is a simple way to help you remember to have your brakes inspected and take better care of your vehicle. It is an easy-to-use resource designed to help you drive smart, save money and make informed decisions.
The Car Care Council is the source of information for the “Be Car Care Aware” consumer education campaign promoting the benefits of regular vehicle care, maintenance and repair to consumers.
The last thing any driver needs is to break down in cold, harsh winter weather. A vehicle check now before winter arrives is a sensible way to be car care aware and avoid the inconvenience of being stranded out in the cold and with the unexpected expense of emergency repairs, says the Car Care Council.
“Winterizing your vehicle before the temperatures drop is a wise idea,” said Rich White, executive director, Car Care Council. “An investment of an hour or two to have your vehicle checked is all it takes to have peace of mind and help avoid the cost and hassle of car trouble during severe weather.”
The Car Care Council recommends the following steps for winterizing your vehicle:
- If you’re due for a tune-up, have it done before winter sets in. Winter magnifies existing problems such as pings, hard starts, sluggish performance or rough idling.
- Have the battery and charging system checked for optimum performance. Cold weather is hard on batteries.
- Clean, flush and put new antifreeze in the cooling system. As a general rule of thumb, this should be done every two years.
- Make sure heaters, defrosters and wipers work properly. Consider winter wiper blades and use cold weather washer fluid. As a general rule, wiper blades should be replaced every six months.
- Check the tire tread depth and tire pressure. If snow and ice are a problem in your area, consider special tires designed to grip slick roads. During winter, tire pressure should be checked weekly.
- Have the brakes checked. The braking system is the vehicle’s most important safety item.
- Have the exhaust system checked for carbon monoxide leaks, which can be especially dangerous during cold weather driving when windows are closed.
- Check to see that exterior and interior lights work and headlights are properly aimed.
- Be diligent about changing the oil and filter at recommended intervals. Dirty oil can spell trouble in winter. Consider changing to “winter weight” oil if you live in a cold climate. Have your technician check the fuel, air and transmission filters at the same time.
Motorists should also keep the gas tank at least half full at all times to decrease the chances of moisture forming in the gas lines and possibly freezing. Drivers should check the tire pressure of the spare in the trunk and stock an emergency kit with an ice scraper and snowbrush, jumper cables, flashlight, flares, blanket, extra clothes, candles/matches, bottled water, dry food snacks and needed medication.

Looking for ways to become more environmentally friendly with your car? Motorists can help protect the environment by following four simple steps from the non-profit Car Care Council.
- Follow a vehicle service schedule including steps like checking engine performance, keeping tires properly inflated, replacing air filters regularly, changing oil regularly and checking your gas cap. Routine maintenance helps reduce emissions and fuel consumption, saving money at the pump.
- Keep your current vehicle longer and limit the number of new cars you buy over the course of a lifetime. Extending vehicle life is as simple as taking care of your vehicle properly. You’ll gain years of reliable service without monthly car payments and higher insurance rates.
- Recycle or properly dispose motor oil, tires, batteries, fluids and other vehicle components to help protect the planet when performing vehicle maintenance or repairs.
- Repower your engine when faced with serious engine trouble. A remanufactured/rebuilt engine can give your vehicle new life and make it more fuel efficient for about the cost of an average down payment on a new car.
“Being car care aware and performing basic vehicle maintenance go a long way toward protecting the environment and improving fuel economy,” said Rich White, executive director, Car Care Council. “The Car Care Council’s free customized service schedule and email reminder service makes it easy to stay on schedule and keep your car running efficiently.”
Owning a car can be a dream or a nightmare depending on how well you take care of your vehicle, says the non-profit Car Care Council. The following are six things that many motorists do that can harm their car and their wallet.
- Ignoring the check engine light.Ignoring an illuminated check engine light can result in serious engine trouble and costly repairs. At the very least, this warning light could alert you to an engine problem that is negatively impacting fuel economy.
- Failing to change fluids and filters. Many fluids are required for the operation and protection of vehicle systems and components. Checking fluid levels regularly, along with the filters, helps ensure that your vehicle runs dependably and extends vehicle life.
- Neglecting your tires. Your vehicle’s tires should be checked frequently for inflation and tread depth. Underinflated tires can wear out more quickly, needing to be replaced sooner, and can negatively impact safety, gas mileage and performance.
- Not following a service schedule.Because many car parts and components wear out or become damaged over time, vehicles need to be routinely serviced in order to perform optimally. Routine inspections and timely repairs will help keep your car running efficiently and will help you avoid more expensive repairs down the road.
- Keeping a dirty car. Allowing your car to go too long without a wash leads to buildup of damaging chemicals and dirt, increases the potential for rust from road salt and interferes with proper visibility needed for safe driving.
- Being a severe driver. Whether it’s stop-and-go traffic, extreme weather, rough roads or heavy loads, it can sometimes be difficult to limit severe driving conditions. However, you can drive smart and improve fuel economy by observing the speed limit; avoiding aggressive driving, including quick starts and stops; not hauling unnecessary items; and keeping your vehicle properly tuned.
“Because auto care isn’t always a top priority for car owners, they might not realize they are doing things that adversely affect the performance, safety and value of their car,” said Rich White, executive director, Car Care Council. “Routine maintenance can go a long way toward saving money, avoiding headaches and protecting your vehicle investment.”
While it may seem like a mundane task, inflating tires is much more crucial to your car than you may think, and it results in a safer and more economical experience on the road. Your vehicle’s handling also will be greatly improved as the larger a tire’s inflated footprint, the more responsive and comfier the ride balance will be.
Because it’s National Tire Safety Week, it’s the perfect time to check your car’s tires.
To find your tires’ proper inflation level, look for a sticker on the driver-side doorjamb. It displays the vehicle weight restriction and tire information. The info is also found in the maintenance or car-care section of your vehicle’s owner’s manual.
Don’t refer to the sidewall markings on your tires, which in part specify the maximum tire pressure — not the recommended pressure.
Unless your tire is visibly flat, don’t judge tire inflation just by looking at it; you have to use a tire pressure gauge to get the correct pounds per square inch reading. There are three types of tire-pressure gauges: digital, internal slide and dial. Prices range from $5 for a basic gauge to more than $30 for one that is digital, has an air-release button — or even talks. All will do the job, but you may want to consider the conditions in which you’ll be using your gauge. “We’ve found that low-cost digital pressure gauges are very accurate and maintain the accuracy longer, but in extremely cold temperatures the gauge may not show up properly,” said John Rastetter, Tire Rack’s director of tire information services.
Tips for checking and filling your tires
Tire manufacturers suggest checking tires when they’re cold for the most accurate reading. Outside temperatures can cause tire pressure to vary by as much as 1 psi per 10 degrees; higher temperatures mean higher psi readings. “Tires are black; what does black do? Attract heat,” Rastetter said, noting the importance of finding a shady place to check and fill all four tires.
Temperature plays a huge part in tire psi, Rastetter said, adding that the most crucial time of year to check pressure is in fall and winter when days are shorter and average temperatures plummet.
Check your tires in the morning before going anywhere, because as soon as you get behind the wheel for an extended amount of time, psi will rise. Rastetter said that if you’ve been on the road a long time and notice higher psi in your tires, don’t let the air out, as the increase in pressure has built up due to the warm, constantly-in-motion tires
What to do
1. Pull your car onto a level surface in the shade.
2. Remove dust caps from the tires’ valve stems.
3. Using your tire gauge, firmly press the tip of the gauge straight on to the tire’s valve stem for a brief moment.
4. The tire gauge should provide a psi reading; if the number seems unrealistically low or high — for example, 85 psi or 1 psi – you will need to repeat the previous step, ensuring that the tire gauge’s tip is properly making contact with the valve stem.
5. If the tire gauge’s recorded reading is higher than the manufacturer-recommended rating, press the gauge tip on the valve stem until you hear air leak out. Check the tire pressure again.
6. If the reading is lower than recommended, fill the tire with air by firmly pressing the air-hose tip onto the valve stem. You will hear air quietly enter the tire. If you hear air leaking or spraying out, you need to double-check that the connection between the air hose and the tire’s valve stem is secure.
7. When you think you’ve added or let out enough air, check the pressure a few times with the gauge.
8. Replace the valve dust caps. Rastetter emphasized the importance of keeping dust caps on during winter driving because if water gets into the valve stem and freezes inside the tire, it could cause a flat.
While you’re at it, check your spare tire’s pressure. You don’t want to have a flat tire and then find out your replacement is flat, too.
Make these steps part of your routine. It will benefit your vehicle and your wallet.
The manufacturer’s maintenance schedule for many automatic transmissions doesn’t call for fresh fluid until 100,000 miles or, with some Ford transmissions, even 150,000 miles. A lot of mechanics say that is too long and it should be done at least every 50,000 miles. Manual transmissions may be on a different schedule, so it’s best to consult the maintenance schedule in the owner’s manual.
Like other vital automotive fluids, transmission fluid deteriorates over time. Hard use — such as frequent stop-and-go city driving, hauling heavy loads, trailer towing — will accelerate the deterioration. That kind of driving raises the operating temperature of the transmission, and heat puts more strain on the transmission and the fluid, which helps facilitate gear shifts, cools the transmission and lubricates moving parts.
If you do a lot of driving under high-stress conditions, you should check the transmission level more often and have a repair shop check the condition of the fluid. Transmission fluid often is red but can come in other colors, and as it deteriorates it tends to turn darker. It may also acquire a burned odor that could indicate it needs to be changed or that the transmission is developing mechanical problems. Another indication it needs changing is dirt or other debris in the fluid. When you take your vehicle in for an oil change or other routine service, the repair facility may urge you to pay for a transmission-fluid change or flush. Even if they can show you that the fluid is darker than original, that might not mean you need fresh fluid right now. Step back, check the maintenance schedule in your owner’s manual and see what the manufacturer recommends before you decide. This also will give you time to price shop.
Many repair shops use flush systems that force out the old fluid and pump in new fluid. Though that sounds good, some manufacturers say you shouldn’t do that (Honda is one; there are others), so you need to know this before you agree to a flush. Look in your owner’s manual. Some manufacturers, such as Honda, also call for their own type of transmission fluid and warn that using other types could cause damage. Moreover, some automatic transmissions have filters that should be cleaned or replaced when the fluid is changed. Make sure the repair facility is using the correct fluid and procedures for your vehicle.
If you have never changed the transmission fluid in your vehicle and have more than 100,000 miles on the odometer, should you change it now? We have seen mixed opinions on this, with some mechanics suggesting you should just leave well alone if you aren’t having shifting problems. Adding fuel to this theory are stories about older transmissions failing shortly after they finally received fresh fluid. We have a hard time accepting that fresh fluid causes transmission failure, so our inclination would be to have it done if you’re planning on keeping the vehicle a few years or longer. However, fresh fluid is not a cure for gears slipping, rough shifting or othermechanical problems, so don’t expect a fluid change to be a magic elixir.
Gasoline is expensive and you’re looking for every way possible to save money at the pump. You already shy away from premium fuel, knowing that your car doesn’t require it. You’d like to save a few pennies per gallon more by going to an off-brand gas station. But you can’t get rid of the nagging fear: Is the cheap gas going to damage your car’s engine?
Edmunds.com put this question to experts in several fields, including an automotive engineer at a major carmaker, gasoline manufacturers and two engineers with the American Automobile Association (AAA). It boils down to this: You can stop worrying about cheap gas. You’re unlikely to hurt your car by using it.
Because of the advances in engine technology, a car’s onboard computer is able to adjust for the inevitable variations in fuel, so most drivers won’t notice a drop off in performance between different brands of fuel, from the most additive-rich gas sold by the major brands to the bare-bones stuff at your corner quickie mart.
Still, spending a few extra pennies per gallon might provide peace of mind to someone who just purchased a new car and wants to keep it as long as possible. People with older cars might not be as concerned about their engine’s longevity. They can buy the less expensive gas and still be OK.
Steve Mazor, chief automotive engineer with the Automobile Club of Southern California, summed it up this way: “Buy the cheapest gas that is closest to you.”
Recipes for Performance — at a Price
But this doesn’t mean that all gas is the same, even though it starts out that way. The fuel from different filling stations comes from a common source: the “base gas” from a refinery. Workers there mix additives mandated by the Environmental Protection Agency into the base gas in order to clean a car’s engine and reduce emissions. Then, the different gas companies — both off-brand and major brands — put their own additive packages in the gas to further boost both cleaning and performance.
A key difference is that the major brands put more additives in their gas and claim to have some secret ingredients. This extra shot of additives provides an additional level of cleaning and protection for your engine.
But is this extra helping of additives, which jacks up the price, really necessary? And, if you don’t use more expensive, extra-additive gas, how soon will your engine’s performance suffer?
“It’s not like any of the fuels are totally junk,” says John Nielsen, director of engineering and repair for the AAA. “If you buy gas from Bob’s Bargain Basement gas station because that’s all that’s available, it won’t hurt your car,” he says.
The real difference is the amount of additives that are in the gas, Nielsen says. More additives essentially afford more protection — but they also cost more.
Some automakers and oil companies believe that the amount of government-required additives isn’t enough to protect engines. They have created a Top Tier gasoline designation. It means that those gasoline brands sell fuels that provide more and better additives.
Nielsen recommends that drivers look in their car’s owner’s manual to see what the carmaker recommends and, when possible, follow that guideline. People who are still concerned about gasoline quality can ask a specific oil company if it has performed independent testing to substantiate its claims.
Selling the Secret Sauce in Gasoline
The major oil companies spend millions of dollars convincing buyers that their gas is superior by creating ads that feature smiling cartoon cars, lab-coated nerds and sooty engine valves. Buy Shell’s nitrogen-enriched gas, for instance, and you won’t get a buildup of “gunk” in your engine, company advertising promises.
Is all this just a marketing gimmick?
“I am a Ph.D. chemist, a nerdy guy who wears a white coat,” says Jim Macias, Shell Oil Company’s fuels marketing manager. “We really believe there are differences in fuels. We can see it, feel it and measure it.”
Macias says the gunk caused by fuels with insufficient additives can foul fuel injectors and even trigger “Check Engine” lights in as few as 10,000 miles.
But not everyone is keen to talk about gasoline quality and whether additives really make the difference.
Edmunds sought comment from one well-known seller of low-price gas: Arco. Arco also often finds itself targeted as being a lower-quality product. BP, Arco’s parent company, did not respond to Edmunds’ interview request.
The American Petroleum Institute provided background comments about fuel additives and promised to provide an expert for an interview. The API spokesman never called back.
Finally, Southwest Research Institute in San Antonio, an independent, nonprofit testing facility, also declined to comment on the question of gasoline quality.
The Skeptics and Their Tests
The Auto Club’s Mazor was more forthcoming, and has some interesting results from a blind test he did on three samples of gasoline from both major and independent gas stations.
“We tested emissions, fuel economy and performance and we could not tell the difference,” he says.
Mazor believes that the driving public has outdated notions about gas. Twenty years ago, onlypremium fuel had detergents in it. Back then, it was beneficial to occasionally buy a tank of high-test gas to clean the engine. Then, he says, “regulations were very lax and there was little enforcement. But all that has changed.”
Likewise, Randy Stephens, chief engineer for Toyota’s Avalon, isn’t wholly convinced by the claims of engine protection afforded by higher-priced gas. He says fuel experts at his company study the effects of different brands of gas on the Toyota engines. Automotive engineers disassemble engines after 10,000 miles of running them on different brands of gas to see if there is a difference.
“Honestly, in the 10 years I’ve been in charge of Avalon, I’ve never seen one come back with any sort of deposit issue,” Stephens says.
Nevertheless, Stephens admits to being “swayed” by ads that tout cleaning agents. Twice a year he adds a bottle of Chevron U.S.A. Inc.’s Techron — the same additive that’s in Chevron gasoline — to the fuel tank of his personal car.
More recently, an investigation into the cause of the accident that killed the actor Paul Walker revealed that the Porsche Carrera GT in which he was riding had nine-year-old tires. The California Highway Patrol noted that the tires’ age might have compromised their drivability and handling characteristics, according to the Los Angeles Times.
These incidents illustrate not only the potential danger of buying used tires but also the perils of driving on aging tires — including those that have never spent a day on the road.
For years, people have relied on a tire’s tread depth to determine its condition. But the rubber compounds in a tire deteriorate with time, regardless of the condition of the tread. An old tire poses a safety hazard.
For some people, old tires might never be an issue. If you drive a typical number of miles, somewhere around 12,000-15,000 miles annually, a tire’s tread will wear out in three to four years, long before the rubber compound does. But if you only drive 6,000 miles a year, or have a car that you only drive on weekends, aging tires could be an issue. The age warning also applies to spare tires and “new” tires that have never been used but are old.
What Happens to a Tire as It Ages?
Sean Kane, president of Safety Research & Strategies, Inc., compares an aging tire to an old rubber band. “If you take a rubber band that’s been sitting around a long time and stretch it, you will start to see cracks in the rubber,” says Kane, whose organization is involved in research, analysis and advocacy on safety matters for the public and clients including attorneys, engineering firms, supplier companies, media and government.
That’s essentially what happens to a tire that’s put on a vehicle and driven. Cracks in the rubber begin to develop over time. They may appear on the surface and inside the tire as well. This cracking can eventually cause the steel belts in the tread to separate from the rest of the tire. An animation on the Safety Research & Strategies Web site shows how this happens. Improper maintenance and heat accelerate the process.
Every tire that’s on the road long enough will succumb to age. Tires that are rated for higher mileage have “anti-ozinant” chemical compounds built into the rubber that will slow the aging process, but nothing stops the effects of time on rubber, says Doug Gervin, Michelin’s director of product marketing for passenger cars and light trucks.
How Long Does a Tire Last?
Carmakers, tire makers and rubber manufacturers differ in their opinions about the lifespan of a tire. The National Highway Traffic Safety Administration (NHTSA) has no specific guidelines on tire agingand defers to the recommendations of carmakers and tire manufacturers. Carmakers such as Nissan and Mercedes-Benz tell consumers to replace tires six years after their production date, regardless of tread life. Tire manufacturers such as Continental and Michelin say a tire can last up to 10 years, provided you get annual tire inspections after the fifth year.
The Rubber Manufacturers Association says there is no way to put a date on when a tire “expires,” because such factors as heat, storage and conditions of use can dramatically reduce the life of a tire. Here’s more on each of these factors.
Heat: NHTSA research has found that tires age more quickly in warmer climates. NHTSA also found that environmental conditions like exposure to sunlight and coastal climates can hasten the aging process. People who live in warm weather and coastal states should keep this in mind when deciding whether they should retire a tire.
Storage: This applies to spare tires and tires that are sitting in a garage or shop. Consider how a spare tire lives its life. If you own a truck, the spare may be mounted underneath the vehicle, exposed to dirt and the elements.
If your spare is in the trunk, it’s as if it is “baking in a miniature oven,” says Dan Zielinski, senior vice president of public affairs for the Rubber Manufacturers Association. Most often, the spare never sees the light of day. But if the tire has been inflated and mounted on a wheel, it is technically “in service,” even if it’s never been used, Gervin says.
A tire that has not been mounted and is just sitting in a tire shop or your garage will age more slowly than one that has been put into service on a car. But it ages nonetheless.
Conditions of use: This refers to how the tire is treated. Is it properly inflated? Has it hit the curb too many times? Has it ever been repaired for a puncture? Tires on a car that’s only driven on the weekends will have a different aging pattern than those on a car that’s driven daily on the highway. All these factors contribute to how quickly or slowly a tire wears out.
Proper maintenance is the best thing a person can do to ensure a long tire life. Gervin recommends that you maintain proper air pressure in tires, have them rotated regularly and have them routinely inspected.
How To Determine the Age of a Tire
The sidewall of a tire is full of numbers and letters. They all mean something, but deciphering them can be a challenge. This Edmunds article about reading a tire’s sidewall goes into greater detail, but for the purposes of determining the age of a tire, you’ll just need to know its U.S. Department of Transportation (DOT) number.
Tires made after 2000 have a four-digit DOT code. The first two numbers represent the week in which the tire was made. The second two represent the year. A tire with a DOT code of 1109 was made in the 11th week of 2009. Tires with a three-digit code were made prior to 2000 and are trickier to decode. The first two digits still tell you the week, but the third digit tells you the year in the decade that it was created. The hard part is knowing what decade that was. Some tires made in the 1990s (but not all) have a triangle after the DOT code, denoting that decade. But for tires without that, a code of “328” could be from the 32nd week of 1988 — or 1978.
Clearly, these DOT numbers weren’t designed with the consumer in mind. They were originally put on tires to make it easier for NHTSA to recall tires and keep track of their manufacturing date.
To make matters worse, you might not always find the DOT number on the outer side of the tire. Because of the way a tire is made, it is actually safer for the technician operating the mold to imprint information on the inner side of the tire, so some manufacturers will opt to put the number there. It is still possible to check the DOT code, but you might have to jack the car up to see it. Keep the visibility of the DOT number in mind the next time you are at a tire shop and the installer asks if you want the tires to be mounted with the raised lettering facing in.
That potential inconvenience is going away, however. NHTSA says that the sidewall information about the tire’s date of manufacture, size and other pertinent data is now required to be on both sides of the tire for easier reading.
After checking out a tire’s birth date, give the rubber a visual inspection. Some of the best advice on such an inspection comes from the British Tyre Manufacturers’ Association. It recommends that consumers check tires regularly for any sign of aging, such as tread distortion or large or small hairline cracks in the sidewall. Vibrations or a change in the dynamic properties of the tire could also be an indicator of aging problems, the association says. It recommends replacing the tire immediately if such symptoms appear.
Don’t Buy Used
Tires are expensive, especially when you factor in the price of mounting and balancing. That’s why used tires become more attractive to consumers who are strapped for cash. But the purchase of used tires is very much a buyer-beware situation, Zielinski says. “Even a one-year-old tire can be dangerous if it was poorly maintained,” he says.
When a consumer buys a used tire, he has no idea how well it was maintained or the conditions in which it has been used. The previous owner might have driven it with low pressure. It could have hit curbs repeatedly. It could have been patched for a nail. Further, it’s a dated product.
“You wouldn’t want a used tire for the same reason that you wouldn’t buy a 10-year-old computer,” Zielinski says. “You are denying yourself the advancements in tire technology over the past few years.”
Make Sure You’re Getting a “Fresh” Tire
Just because a tire is unused doesn’t mean it’s new. In a number of instances, consumers have purchased “new” tires at retail stores only to find out later that they were manufactured years earlier. In addition to having a shorter life on the road, a tire that’s supposedly new but is actually old may be past its warranty period.
If you buy tires and soon after discover that they’re actually a few years old, you have the right to request newer ones, Zielinski says. Any reputable store should be willing to make amends. “It is fair for a consumer to expect that ‘new’ is not several years old,” he says.
Getting rid of an unused spare or a tire with good-looking tread may be the hardest thing for a thrifty consumer to do. “Nobody’s going to take a tire that looks like it’s never been used and throw it out,” Kane says. But if it’s old, that’s exactly what the owner should do.
Although Kane has lobbied NHTSA to enact regulations on tire aging, nothing is currently on the books. A NHTSA spokesman says the organization is “continuing to conduct research into the effects of tire aging, and what actions consumers can do to safely monitor their tires when they are on their vehicles.”
It’s too bad that tires don’t have a “sell by” date, like cartons of milk. Since there’s no consensus from government or industry sources, we’ll just say that if your tire has plenty of tread left but is nearing the five-year mark, it’s time to get it inspected for signs of aging.
Of all your vehicle’s components, tires have the greatest effect on the way it handles and brakes. So if the tire store recommends new tires at your five-year check-up, spend the money and don’t put it off. Your life could depend on it.
