How many miles do you replace tires


Guide to How Long A Tire Lasts

The question, "How long does a tire last?" tends to be followed by several others like, “What causes a tire to wear? When should tires be replaced? What can be done to make tires last longer?” Fortunately, we can help provide clarity around these questions.

HOW LONG A TIRE LASTS


There is no exact answer to how long a particular tire will last, but there are things a driver can do to get the most out of their tire investment and avoid driving on unsafe tires. On average, people drive between 12,000 to 15,000 miles a year, which means the average good quality all-season tire will last somewhere between three and five years, depending on maintenance, driving style and conditions, etc.

 The National Highway Traffic Safety Association (NHTSA) states a driver is three times more likely to be involved in a crash caused by poor tire condition. Safer is smarter when it comes to the health of tires, so if there is ever a question on tread wear or age, have the tires checked.

FACTORS THAT INFLUENCE HOW LONG A TIRE LASTS

Multiple factors play a role in how long a tire may remain in service. Miles driven, road conditions, driving style, maintenance and age all affect how long a tire lasts.

Worn vs. Aged

Tires naturally wear the more they are driven and worn out tires provide reduced traction compared to those with adequate tread, especially in adverse weather conditions.  Most drivers understand worn out tires (remaining tread depth at or below 2/32”) should be removed from service.

Many drivers are not aware that minimally used tires, like the ones on recreational vehicles, collectible cars, or even spare tires, tend to experience aging instead of wearing, due to a lack of driving. An aged tire has a substantial amount of tread; however, the structural integrity of the tire is weaker because the tire needs to be driven for the chemicals in the rubber to remain effective.

Curbs, Potholes, and Other Hazards

Hitting curbs or driving on roads in poor condition (potholes, broken pavement, poorly graded railroad crossings, unpaved roads, etc. ) can cause misalignment, and suspension damage that affects tire wear. If your daily drive includes these challenges, be sure to schedule annual suspension, alignment and tire checks.

Weather Conditions

Driving in poor weather conditions like ice, snow, and rain can cause tires to wear quicker because they must work harder to maintain traction. Purchasing tires that are specially engineered to perform in specific weather conditions can provide drivers with an extra measure of traction and control (meaning greater safety) while delivering good treadwear.

Bridgestone offers different types of tires designed to keep you and your car safe during any weather or road condition. For example, Bridgestone's Blizzak tire series is built to perform in harsh winter weather conditions providing durable traction on snowy and icy roads, and the Dueler tire series is one of several that offer a secure grip on wet road conditions for areas that experience heavy rain.

Poor Driving Habits

Poor driving habits like hard cornering, quick acceleration, and sudden braking can increase the stress on tires tremendously, causing them to wear rapidly. Drivers can extend the life of their tires significantly by avoiding aggressive driving.

Neglected Maintenance

It is important to regularly have tires checked for damage, to maintain air pressure levels, and to keep tires aligned and rotated. Without proper maintenance, tire life can be reduced by as much as half - even more, in some cases.

KNOWING WHEN TO REPLACE TIRES

If the below signs are evident with your tires, it may be time to have them replaced. 

Low Tread Depth

Tread loss is a significant sign a tire needs to be replaced. Low tread is a sign driver can physically see happening on their tire. Depending on the part of the tire that is wearing, there may be other problems with the vehicle.

    Pronounced inner or outer shoulder wear: tires are misaligned

    Edge of the shoulder wear: tires are under-inflated, need to be rotated or both.

    Center wear: tires may be overinflated or have been subjected to extremely hard acceleration.

    Cupped wear: the vehicle is experiencing suspension problems

    All tires have tread wear indicators built-in, but if the tread looks low take time to do the penny test on the tires.

    Rough Drive

    If you’re experiencing a vibration (particularly if it just started), or high (and increasing) levels of tire noise it may be a sign your tires are out of balance, not wearing properly or have a structural issue.  In some cases, this may affect safety, so have your tires checked by a qualified professional asap.

    DOT Number

    The U.S. Department of Transportation (DOT) number on the tire’s sidewall is another way to help keep track of when they need to be replaced. It’s easy to identify - look for the letters “DOT” followed by eleven or twelve letters and numbers.  On tires made after the year 2000 the final four digits signify the week and year of manufacture. So, a tire with “3618” would have been made in the 36th week or 2018. A tire that has a 3-digit week-and-year code means the tire was made before the year 2000 and should be replaced due to age.

    Bridgestone recommends that its Bridgestone or Firestone brand tires be removed from service after ten years regardless of their remaining tread depth.  They also recommend periodic inspections by a qualified technician for damage such as punctures, impact damage, signs of improper inflation or overloading, or other conditions resulting from the use or misuse of the tire.

    HOW LONG A TIRE LASTS: EXTENDING TREAD LIFE

    Tires are both one of the largest maintenance expenses a vehicle owner is likely to face, and one of the most critical in terms of driving safety and performance.  For both reasons it’s important to care for them properly. Bottom line: good maintenance and driving habits help keep drivers safe, and it saves them money by extending tire life.

    Easy Does It

    Tire life can be reduced by as much as half when they’re subjected to a lot of hard braking and aggressive acceleration from a standstill.  Avoiding tailgating to reduce the need for frequent hard braking will increase tire life. Easing into the throttle when pulling away from a stop reduces strain on the tires and improves wear. Slowing before sharp corners also reduces stress on tires, as does avoiding potholes and broken pavement when possible. If you’re interested in spending less on tires, following these steps can help.

    Regular Maintenance

    Another way to extend tire life is to keep up with the proper maintenance of a vehicle and its tires. A couple of things you can do yourself are to check the air pressure and tread depth.  You should have a qualified technician periodically check their balance and alignment and be sure to have tires rotated at regular intervals. maintenance is essential for your tires to perform their best and last their longest.

    How Long Should a Set of Tires Last?

    It may be tentative, but tires do have an expiration date. There is a general consensus that most tires should be inspected, if not replaced, at about six years and should be absolutely be swapped out after 10 years, regardless of how much tread they have left. How do you know how old your tires are? There’s a code on the sidewall that you can read about here. Wear is a far more straightforward consideration: Tiremakers and safety advocates say a tire is worn out when its tread depth reaches 2/32 of an inch. That’s all fine, but what most car owners want to know is how long to expect a set of new tires to last before they need to be replaced.

    “I wish it were simple to say how long each tire might last, but tires are different,” said Dan Zielinski, a spokesman for the U.S. Tire Manufacturers Association (USTMA). “Some tire manufacturers offer a warranty as high as 80,000 miles or more, reflecting confidence in that particular product’s longevity based on its engineering, technology, and design. Other tires may be built to provide 30,000 miles of service.” Or less; some high-performance tires on cars driven aggressively will be worn to the 2/32-inch point without ever seeing 15,000 miles, but those are extreme cases.

    The average American drives between 14,000 and 15,000 miles a year, according to data from the Federal Highway Administration. Zielinski said that, if you’re kind to your tires—that is, you aren’t constantly peeling out at stoplights and you properly maintain them—most new tires on the market today will last about 60,000 miles. For what it’s worth, the USTMA did a review of several thousand recently scrapped tires and found that most were three to four years old. There was no way of telling how many miles were on those tires, but it’s easy enough to multiply four years by 15,000 miles annually to confirm the rough approximation of tire durability.

    If you want to figure out how soon you’ll wear out the tires on your car, Zielinski said it would be a good idea to start by determining how many miles you drive each year. Divide the number of miles on the odometer by how many years you’ve owned the car (starting, obviously, from when you first got the car and accounting for any mileage it had on it at that time). Then you can compare that with any advertised warranty on the make and model of the tires and figure out how many years of service to expect. If you live where winter tires are advisable and swap those onto the car for some months of the year, your regular tires will get less use and will endure for a longer period of time, but remember the caveats about tire age.

    Zielinski also noted that if you hit the wear bars at 50,000 miles on a set of tires with a 60,000-mile warranty, for example, tiremakers that offer such coverage will typically prorate the price of a new set. In this example, you could expect a discount on the new set equal to one-sixth their price, or about 17 percent. You might not get it, though, if you decide to change brands.

    In general, the best way to preserve the life of your tires, and keep yourself and your passengers safe, is to maintain them properly. Here are some tire basics and maintenance tips:

    Tread

    A tire is considered unsafe, and should be changed, once its tread is worn down to 2/32 of an inch, according to the National Highway Traffic Safety Administration (NHTSA). Many tires have tread-wear indicators, which are little bars in the tread that show when the tire is worn down to replacement level. These will start making noise to alert the driver that they need attention. You can also use a penny: NHTSA recommends putting the penny in the tread with Abraham Lincoln’s head upside down and facing toward you. If you can see the top of Abe’s head, it’s time for new tires.

    Pressure

    To ensure even wear, tiremakers and auto companies recommend that vehicle owners check their tire pressures monthly. The pressure should be at the vehicle manufacturer’s recommended level, which is usually found in the car or truck’s doorjamb or in the owner’s manual. One quick and easy way to check tire pressure is with a handheld tire-pressure gauge, which you can find starting around $10 at an auto-parts store. Tire shops will often check the pressure for you. Some gas stations have digital readouts as part of their air pumps; these are not always accurate, though. It’s best to check the pressures when the tires are cold, meaning that they have not been driven on for several hours. So you’re better off checking them at home after the car has been parked overnight.

    Balance and Alignment

    Tires need to be round, and the tire/wheel combination needs to be balanced. Tire shops and mechanics will use a balance machine, which spins the wheel to see where high and low spots are and detects any imbalance. The tire shop will then add weights, which are hammered onto the wheel, to balance them. These shops can also make make sure your wheels are aligned to keep the car tracking straight, which also reduces tire wear.

    Rotation

    Rotating your tires can help prolong their lives. For front-wheel-drive vehicles, the tires in the front will wear more quickly and can be swapped with the rear ones. The inverse is true for rear-wheel-drive cars and trucks. All-wheel-drive models, too, may need rotation. Most owner’s manuals contain a recommended pattern for rotating tires to spread the wear evenly. The USTMA recommends tires be rotated every 5000 to 8000 miles.

    7 rubber signals: what the tire says about car problems

    How do you know when tires are completely worn out and it's time to change them? Everything is simple. For summer tires, the limit is 1.6 mm of residual tread depth, and for winter (or all-season tires used in winter) - 4 mm. Modern summer tires can travel from 40,000 to 70,000 km, depending on driving style and vehicle characteristics. An average motorist rolls such a mileage on summer tires in 2-3 seasons. Moreover, wear implies not only a decrease in tread depth. For millions of cycles of deformation, the strength of the carcass and its adhesion to the layers of the rubber compound are violated. In short, every 2-3 years you should buy a new set of tires. nine0003

    In case of irreparable damage to one of the tires and a relatively high total mileage of the kit, it is also worth considering replacing it. Well, or about buying at least a pair of new tires, which, for any type of drive, should be installed on the front axle. We put two tires back - the most decent of the remaining ones.

    What if I don't drive much?

    Many motorists drive only a few thousand kilometers a year. This does not mean that the tires will serve you for several decades. According to Russian requirements (GOST 4754-97), the service life of passenger car tires is 5 years from the date of manufacture. And for example, Continental recommends that all car tires (including the spare tire) older than 10 years old should be replaced with new ones. Therefore, with small runs, you can navigate for ten years. The date of manufacture of the tire is indicated on the sidewall. Usually it is an oval with four numbers. The first two are the ordinal number of the week in the year, the last two indicate the year.

    How to change the car yourself - detailed instructions

    Tires should be rotated periodically in accordance with the vehicle manufacturer's recommendations - information on this can be found in the owner's manual.

    We can advise you to carefully use the tires and, most importantly, to store them correctly in the off-season. First of all, during storage, it is important to exclude direct sunlight from hitting the tires, which greatly age the rubber. Tires without rims should be placed vertically, and stacked on rims. nine0003

    And before installing tires on a car at the beginning of the season, evaluate their condition. There should be no cracks in the tread and sidewalls. The tire should not be dry, it should remain rubbery and not look like baked plastic.

    Driving on badly worn tires - will I be fined or not?

    Winter tires have a much shorter life span. They almost always fail due to the wear of the treadmill, because the tread of a new tire is 7–8 mm, and only 3–4 mm remain working height. If the tires are studded, then with such wear there are very few metal elements left, and the tire will not provide adequate safety when driving on a winter road. However, not only spikes, but also Velcro, with such a degree of wear, also lose most of their capabilities. nine0003

    The real life of winter tires rarely exceeds 30,000 km. "Bald" winter tires without studs can be re-rolled in summer, but their grip on hot road surfaces will be very poor. This must be taken into account, especially when braking.

    ***

    So: tires that have not yet worn out along the tread (that is, up to 1.6 mm tread depth for summer tires, 4 mm for winter tires) are changed either ten years after the date of issue, or when the rubber layer cracks tires or damage. nine0003

    There is no definite answer. It depends on which tires you bought first, how much you ride, how you ride, in what conditions.

    How often do you change tires? I will buy a new one and go about 30 km a year, changing tires every 3-4 years. I know people who have been riding the same bald tires for 10 years, but it's very dangerous and irresponsible.

    It is worth being able to read the age of the tire because the tire also ages.

    The date of manufacture of the tire is written on the sidewall of the tire, behind the DOT symbol next to this symbol.

    There may be something else with this point, not just the age of the tires.

    The production date of this tire is indicated by 3 or 4 numbers with additional embossing. Pay special attention to tires with a three-digit marking. Such tires are very old - at least 3 years old, because such models were produced before 20 years. nine0003

    The four-digit strings are new tires and can be deciphered: the first two numbers indicate the week and the last two numbers indicate the year the tires were manufactured. A year has just over 4 weeks.

    Example: 1410 means that the model was made on the 14th week of 2010, i.e. in 2010 sometime in the first half of April.

    Polish regulations state that the tread depth must be at least 1. 6 mm.

    But this 1.6 is the last resort, and then there is less grip, it is better not to wait until the tread becomes so shallow and replace the tires earlier. Especially if we drive a lot or drive fast.

    In winter tires, the gap depth between the blocks must be at least 4 mm, and in summer tires - 3 mm - this will prevent our car from skidding. nine0003

    Each tire is also equipped with a special TWI tread wear indicator. It is marked with a triangle symbol.

    The best tires also sometimes have additional indicators showing tire wear and suggest tire replacement.

    I change tires when I vulcanize, suggest I do. Cool people work alongside me in vulcanization, and you can always rely on their reliable opinion. When they say I need to change tires, I change tires.

    I also rely on the opinion of a vulcanizing specialist. I use a shop where you can buy new and used tires locally. I know they don't cheat me for profit. I have known them for over a decade and I have an idea about tires.

    I rely on professionals who change tires every season. They know this, and when the time comes, they recommend replacing old tires with new ones.
