In general terms a passenger vehicle tire with a 300 UTQG was not designed for longevity. You will generally see a 300 UTQG on tires which are high performance tires or are simply off lesser quality. Such a tire will usually only “last” approximately 15k to 30k miles.Treadwear grade: A government-required number that indicates a tire’s expected wear. A grade of 300 denotes a tire that will wear three times as well as a tire graded 100.For example, treadwear 400 will mean every 1/32” wears every 8,000-10,000 miles. However, hard rubber provides a rather rough ride, while softer rubber performs better and soothes the move.

What is a treadwear rating of 300?

Treadwear grade: A government-required number that indicates a tire’s expected wear. A grade of 300 denotes a tire that will wear three times as well as a tire graded 100.

How many miles is 400 treadwear?

For example, treadwear 400 will mean every 1/32” wears every 8,000-10,000 miles. However, hard rubber provides a rather rough ride, while softer rubber performs better and soothes the move.

How many miles is 200 treadwear?

A tire rated at 200 has a projected tread life of 60,000 miles.

How many miles is 560 treadwear?

Theoretically, a tire with a UTQG grade of 800 should last twice as long as one rated 400. Some scores from the tests followed the tire makers’ claims fairly closely. For example, four models that had modest tread-wear grades (520 to 560) and warranties (65,000 to 75,000 miles) scored fair in CR’s wear-test ratings.

How long do 40000 mile tires last?

The straightforward answer is “it depends.” A normal set of tires should last for 60,000 to 75,000 miles, or about four to five years. But there are a few key factors that will affect your tires’ lifespan.

What is a good treadwear rating on a tire?

Tires with treadwear ratings of 350 or less tend to have some performance pretentions, but for serious drivers and competitive racers, the only tires they will ever consider have treadwear ratings of 200 or less.

What does a treadwear of 500 mean?

If the tire being tested gets a 500-tread wear rating, that means it’s expected to take five times as long to wear out as the control tire. The tread wear grade designation is defined when the tire is run a 640 kilometer course for 11,520 km, with tread depths being measured every 1,280 to give a projected tread life.

Is 540 a good treadwear rating?

A treadwear rating generally falls between 60 and 540.

Is 400 a good treadwear rating?

The 400 is tread wear which represents the tire’s comparative wear when measured against the governments mandated tire, which is rated at 100. So the tire rated at 400 would wear four times longer than the government’s mandated tire. However, please don’t link treadwear grades with your projected tire mileage.

How do I check my treadwear rating?

You can find the UTQG tire ratings on both your tire’s sticker label and molded onto the tire sidewall. Developed by NHTSA, the UTQG system scores tires on how well they perform when it comes to treadwear, traction and temperature.

How do you read tire treadwear?

In basic terms, and in the spirit of the concept, the higher the UTQG treadwear rating, the greater the tire life. A tire with a “600” treadwear rating is forecasted to last twice as long as a tire with a “300” rating, and should accumulate three times the mileage of a “200” rated tire.

How many miles is a 540 treadwear?

Those Confusing & Contradictory Grades Treadwear Grades Compared to Stated Warranties
Mileage Warranty Brand Type UTQG Rating
House 640
85,000 Major 540
Major 700
100,000 Major 700

Is 640 a good treadwear rating?

On the other end, today’s more durable tires carry UTQG tread wear grades of 640, 720 or even 820—meaning they will last up to six times as long as those expensive high-performance lines. Long-lasting tires when new sometimes carry tread wear warranties of 60,000 to 80,000 miles.

How many miles is a 700 treadwear rating?

A general rule of thumb sometimes used is that an average driver with an average vehicle can typically estimate the tread life of a tire by multiplying the UTQG treadwear rating by 100. For example, a tire with a treadwear rating of 700 may last approximately 70,000 miles.

What is a 500 treadwear rating?

If the tire being tested gets a 500-tread wear rating, that means it’s expected to take five times as long to wear out as the control tire. The tread wear grade designation is defined when the tire is run a 640 kilometer course for 11,520 km, with tread depths being measured every 1,280 to give a projected tread life.

What is a 400 treadwear tire?

The 400 is tread wear which represents the tire’s comparative wear when measured against the governments mandated tire, which is rated at 100. So the tire rated at 400 would wear four times longer than the government’s mandated tire.

What is the highest treadwear rating?

Treadwear is determined by comparing the subject tire against a control tire that is assigned a grade of 100. If the subject tire gets a grade of 200, it can be expected to last twice as long as the control tire; a tire with a grade of 80 usually is less durable. Currently, the highest reported treadwear rating is 700.

How many miles is a 700 treadwear rating?

A general rule of thumb sometimes used is that an average driver with an average vehicle can typically estimate the tread life of a tire by multiplying the UTQG treadwear rating by 100. For example, a tire with a treadwear rating of 700 may last approximately 70,000 miles.

The Truth About Tire Treadwear

Many replacement tires, especially the all-season ones that come standard on a car, minivan, or SUV, have a prorated mileage warranty. It’s based on how long the tread on a tire is expected to last. For the tires in our ratings, it is usually between 50,000 and 90,000 miles. But those warranties often don’t offer the consumer much payback if the tires wear out prematurely. If tires wear out before the warranty mileage is used up, you’ll probably get only a fractional credit representing the miles the tires didn’t cover. And that’s good only toward the purchase of identical or comparable tires from the same manufacturer—which you may not want. You can’t use it to get better tires or tires from another brand.

Here’s where the math really doesn’t add up: The credit can be applied to a manufacturer’s suggested retail price for a new tire or to a dealer’s price. And that price is often high relative to the frequent discounts offered by many retailers. In fact, you may be able to buy new, discounted tires for less than the price of warranty replacements.

On top of that, restrictions to get your prorated credit abound. Your tires may have to show even wear across the tread or the deal’s off. You may also have to show receipts that verify you had the tires rotated at the prescribed intervals, usually every 5,000 miles, since they were new.

The tires also have to be worn out, which is defined as having a tread depth of only about 2/32 inch. Tires that are worn out will perform poorly on wet roads and could pose a safety risk. (Learn more about tire warranties.)

Our controlled tread life tests cut through the marketing mumbo-jumbo to tell you how many miles your tires will last before becoming worn out. Of course, your actual experience will vary according to the vehicle you drive, how and where you drive, routine maintenance, and other factors.

How Long Can Used Tires Last?

Normally, used tires last 2-5 years if bought in adequate condition. A 2-year-old tire with no damage, patches, uneven wear, and with about 8/32” tread left, may last for good 5 years. A 4-year-old tire with 5/32” tread left, and without any significant plugs or cuts, may last a further 2 years. The lifespan of a used tire is extremely unpredictable, so any calculations are only estimates. The tire’s condition greatly depends on a number of factors.

What Influences How Long Used Tires Last?

The main factors influencing how long a used tire will last are:

Age

Treadwear

Damage and repairs

Maintenance.

[insert page=’2137′ display=’content’]

Age

Any tire of 5 years or older has to be fully diagnosed every year and changed once deep cracks appear on its sidewalls or tread. So, if you’re looking for a used tire, a 2- or 3-year-old one will do fine. Tires over 10 years old can fail at any moment, as the rubber is too old to hold together. It starts to deteriorate the day the tire is released from the plant.

The National Highway Traffic Safety Administration and the Rubber Manufacturers Association don’t give an exact tire expiration age. However, in 2014, NHTSA released a document showing they are working on the issue. Vehicle manufacturers recommend changing tires once every 6 years, while tire manufacturers, like Michelin, say used tires last up to 10 years.

Determining Tire Age

You can determine tire age by looking at the DOT code on its sidewall. The last four digits are the week and the year the tire was manufactured. So, if you look at a tire with the code 4708, this will mean the tire was made during the 47th week of 2008. Such a tire is already too old to buy, unless it’s in perfect condition and you only need the tire for a maximum of one year.

You can learn more about tire date codes from this article.

Treadwear

Used tires may have up to 10/32” tread available, which is more than 90% of a new tire. Used tires last to 2/32”, which is the legal treadwear limit but now often considered too shallow. At this point, the braking distance increases, the vehicle’s response becomes worse, and the tires may fail. To get adequate service from used tires, aim at 7/32” or more. Learn more about used tire tread and other things you have to be aware of from this post.

Also pay attention to the Uniform Tire Quality Grade (UTQG) rating on the tire. There are three aspects: traction, treadwear, and temperature. The word “treadwear” and a three-digit number following, is what you should look for. The bigger the number is, the longer the used tires last, and the harder their rubber is. For example, treadwear 400 will mean every 1/32” wears every 8,000-10,000 miles. However, hard rubber provides a rather rough ride, while softer rubber performs better and soothes the move.

[insert page=’1887′ display=’content’]

Uneven Wear

Irregular wear indicates a number of neglected vehicle issues. The wheels may be misaligned, the tires imbalanced, the suspension worn out, etc. Used tires last much less time if they are wearing unevenly. If one part of the tread wears beyond the legal limit, the tire’s performance will deteriorate dramatically. Plus, irregular wear may cause vehicle vibration, suspension failure, and other dangerous issues.

How Long Winter Tire Tread Lasts

It’s important to remember winter tires should be considered worn out at 4/32”. They catch onto snow with the help of special thin grooves called sipes. When these grooves become shallower, they don’t catch as successfully, so the tire will start to slide. Eventually, braking and cornering will become more difficult, and it will be easier to lose control of the vehicle.

So, used tires last for less time if they are for winter use, which you should consider when buying.

Damage and Repairs

The most frequent damage you need to pay attention to are cuts, holes from plugs, bulges, and cracks. While plug holes can be repaired, other damage are rarely reparable. There are also other serious issues to be aware of, such as:

Exposed cords.

Severe irregular wear can make steel cords show on the surface. This is a serious issue that may cause tread separation.

Severe irregular wear can make steel cords show on the surface. This is a serious issue that may cause tread separation. Belt separation.

Bumps or bulges on the sidewall may indicate internal damage – specifically, belt separation. It usually happens when the vehicle drives over a large curb or pothole, at a high speed.

Bumps or bulges on the sidewall may indicate internal damage – specifically, belt separation. It usually happens when the vehicle drives over a large curb or pothole, at a high speed. Bead chunking.

If you see chunks of rubber missing from the bead area, consider the tire dangerous. The bead may come off the rim at any moment, as the damage expands. Plus, such a tire will lose air more than the others , which may result in a blowout .

Any damage to the liner may cause air loss, a sidewall collapse, etc. The tire may just fold and immediately fail. Also, if you find rubber dust inside the tire, it’s probably damaged, as the sidewalls were scrubbing themselves off at some point.

As for repairs, used tires last longer without them. However, if the tire is in perfect condition but has one repaired plug, it may still serve well. But keep in mind, other damage usually isn’t reparable, so if you see a sealed crack or cut, don’t buy such a tire.

Why Tires Get Damaged

Some of the reasons for premature cracking, cuts, bulges, and other damages are:

Hitting obstacles, potholes, curbs

Getting a nail/screw in the tire by driving over a it

Driving in extreme temperatures

Excessive exposure to ozone, oxygen, oil, harmful chemicals

Rapid speed acceleration, hard cornering or braking

Under-inflation, over-inflation

Driving on a tire that ran flat

Neglecting basic tire maintenance

Improper usage (street tires off-road, winter tires in summer, etc.).

Maintenance

Both prior and future maintenance are crucial to how long used tires last. However, the necessary processes are the same:

Tire balance

Tire rotation

Wheel alignment.

Tire Balance

Many tires have stiff spots around their circumference. These spots must be balanced by putting small weights opposite them. You can perform such a procedure at home or go to a mechanic, where they will check the tire with a computer and balance it.

It’s an important part of tire maintenance, as imbalance may cause vibrations at speeds of 45 mph and more. The vibration can cause cupping or patch-wear – an irregular wear pattern that looks like scoops of rubber were taken out around the tire’s shoulder. So if you see a tire that has such wear, don’t buy it. You will have to wait for the tire to wear past the pattern, but by that time it may be worn out. Moreover, such a tire will produce noise and may also cause vibration.

Used tires last much longer when they are balanced after mounting. So, if you buy one, make sure you take it to a mechanic or find the stiff spots yourself. Learn more about tire balancing and how to perform it here.

Tire Rotation

Tire rotation is important, as it prevents uneven wear and helps used tires last longer. Weight distribution between the four main tires isn’t equal, due to the engine and transmission adding more mass. Consequentially, more weight is applied to one tire/pair of tires than to the others, due to which they wear unevenly. Tires with more mass on them wear faster, so tire rotation evens the wear.

You can read more on the importance of tire rotation and ways to do it in this article.

Wheel Alignment

Wheel alignment sets each wheel parallel to the others and perpendicular to the road. This procedure is often confused with tire balancing, however, they are completely different processes. There are three angles in wheel alignment: camber, caster, and toe. Zero camber means the wheel is perpendicular to the ground. Zero caster means the steering axis is perpendicular to the ground. Zero toe means the wheels are parallel to each other.

If any of the settings are out, tires wear unevenly, causing any of the aforementioned issues. Furthermore, wheel misalignment may cause suspension failure or premature wear.

NOTE: All these procedures are mentioned in the NHTSA special education campaign TireWise. On the special Maintenance page of the project, you can find out what’s important for your tires. All the rules usually apply to used tires, too.

How Long Used Tires Last if Unused

Stored used tires last for the same amount of time as tires you mount on your vehicle – a maximum of 10 years since the date of their manufacture. Rubber ages independently from usage of the tire, as the process of oxidation happens regardless of use.

There are two factors influencing the tire’s lifespan in this case:

Environmental conditions.

Oxygen, ozone, ultraviolet light, and heat, make rubber age and dry. The more of these factors present, the faster the tire will become unfit for use.

Oxygen, ozone, ultraviolet light, and heat, make rubber age and dry. The more of these factors present, the faster the tire will become unfit for use. Storage conditions.

The amount of light, temperature in the storage room, humidity, and tire deformation, influence tire condition. Exposure to the environmental conditions is also a part of storage. The hotter and lighter, the faster a tire ages. The more deformation there is (if tires lie in a pile or hang without rims), the faster the damage will occur.

Some used tires even last longer when actually used on a vehicle. When a tire is spinning, the oils within it start moving and lubricating the rubber from the inside. This prevents premature drying, making the tire last a bit longer. Therefore, you can choose used tires from different brands, for example Hercules, and not be afraid that their service life will be very short. If you want to know more about tire storage, read this article.

How to Make Used Tires Last Longer

There are some things you can do to prolong the life of your used tires. These are:

Check air pressure regularly.

Some people recommend to check tire pressure every 3,000 miles, others insist on doing it weekly. It depends on the roads you drive on and the symptoms your tires have. For example, if you notice a tire loses air slowly yet faster than the others, check the pressure more often.

Proper inflation will improve your fuel efficiency by up to 3%. Nowadays, checking the inflation rate isn’t difficult, due to the Tire Pressure Monitoring System. It’s required on all vehicles manufactured after 2007.

Rotate your tires.

To make your used tires last longer, make sure you rotate them every 5,000-8,000 miles. Also, look at the tires thoroughly while rotating, as there may be minor damage that could become a serious issue. Remember to choose the right rotation pattern for the tires, depending on whether they are directional and same-sized.

Remember to choose the right rotation pattern for the tires, depending on whether they are directional and same-sized. Balance your tires.

Balance the tires every 3,000-6,000 miles, depending on how fast the tread wears. With time, weight distribution around the tire changes, requiring a new balance. It’s important to provide balance, to avoid vehicle vibration and other connected issues.

Some exposure is inevitable, but make sure you control the climate in your garage, to make the used tires last longer. Storing tires in a cool dark place, in special tire totes, will help prolong their life. When not at home, make sure you park the car in shade.

Follow special techniques and rules of tire cleaning to achieve the best results. The easiest way to clean your tires is to change the water every time you wash or rinse one tire. Another rule is to dry clean them first and then apply water. Keep in mind, some cleaning substances promote tire drying, so make sure you choose the appropriate cleaners.

Buying Used Tires: Yes or No?

Used tires last almost as long as new ones if you check them for damage, uneven treadwear, etc., before buying. They will also save you money, as you can often find a set that usually costs $1000, for just $200. Furthermore, you will be helping the environment, as there are millions of reusable tires thrown away every year. There is more information on the benefits of buying used tires here.

However, keep in mind, used tires have no warranty, so you don’t know for sure what you are buying. Some sellers may lie about the maintenance they provided on the tires and any internal damage. The tire code may be scrubbed off, preventing you from learning its real age. Anything suspicious may mean there’s an issue with the tire you are about to buy, so be cautious. You can learn more about the drawbacks of buying used tires here.

Considering all pros and cons, the used tire market is still blooming. About 30 million tires are sold every year, which is only 10% of the whole tire market.

Road-testing the accuracy of tire tread-wear ratings

Until now, you had to trust the tread-wear ratings on the sidewalls and a tire’s tread-wear warranty to tell you how long your tires would last. Consumer Reports’ new tests show that claims don’t always meet reality.

Some tire makers, CR found, overestimate tread wear. Others underestimate it. And warranties are prorated: You get only partial credit toward a new tire based on the difference between the mileage on your worn-out tire and the warranty’s mileage threshold. (Tread is considered worn out when it reaches the industry norm of 2/32-inch deep.) Most warranties don’t cover damage resulting from potholes or other road hazards.

The magazine recently included results of its own tread-wear tests in ratings of all-season tires — the kind that are standard on most new cars and light trucks, and that accounted for 83 percent of the replacement market last year. In addition to CR’s usual tests measuring handling, braking, and ride comfort under a variety of conditions, the magazine commissioned accelerated wear tests that closely followed the same procedures specified by the government for manufacturers.

For the all-season tires tested, manufacturers’ tread-wear ratings (the Uniform Tire Quality Grades found on a tire’s sidewall) range from 520 to 740. Theoretically, a tire with a UTQG grade of 800 should last twice as long as one rated 400. Some scores from the tests followed the tire makers’ claims fairly closely. For example, four models that had modest tread-wear grades (520 to 560) and warranties (65,000 to 75,000 miles) scored fair in CR’s wear-test ratings. Likewise, a tire with a 700 UTQG grade and an 80,000-mile warranty had excellent tread wear in the tests.

But others didn’t come close. One would expect a model that claims a high 700 grade and 80,000-mile warranty to provide at least “very good” tread life. The Kelly Navigator Platinum TE, however, could manage only “fair.” Conversely, the Daytona Grenadier PLE has a more modest 640 grade and an 80,000-mile warranty, yet has excellent wear rating based on the tests.

The magazine’s editors say they believe CR’s tread-wear ratings are the best indicator of true tire-wear potential. The manufacturer’s warranty is your second-best option, as a failure to meet this claim could mean that the tire maker must reimburse you some of the tire’s price. Use the manufacturer’s UTQG tread-wear grades as a loose guideline.

In the tests, two Michelin all-season models emerged as best for all weather conditions. (Prices are per tire for size P205/65R15, where “15” denotes the wheel diameter in inches. You can expect similar performance for 14- through 17-inch sizes of the same models.) The Michelin X Radial ($111, sold only to members of shopping clubs), is a very good all-around performer. The Michelin HydroEdge ($100) performs capably, but is noisier than its brandmate.

If driving on icy roads isn’t a factor, consider the top-rated Goodyear Assurance TripleTred ($80), the Hankook Mileage Plus II H725 ($50), and the Yokohama Avid TRZ ($70). These tires do everything well, except braking on ice.

And if long tread life is important to you, CR recommends four models: the Michelin HydroEdge and Yokohama Avid TRZ noted above, plus the Dayton Grenadier PLE ($48) and the Bridgestone Turanza LS-T ($78). The Dayton and Bridgestone trail the others in overall performance. Of those four, only the Michelin HydroEdge scored better than “fair” for braking on ice, and the Bridgestone lagged in snow traction.

Consumer Reports recommends discarding your tires before they get to the 2/32-inch mark.
