What is a good treadwear rating?
Most tires used on passenger vehicles have a treadwear rating that falls between 200 and 500. Tires in this bracket offer a great mix of grip and safety, matched with enough longevity to last multiple years if not driven hard every day. Tires with medium treadwear are therefore excellent for everyday driving. While not even the best UTQG-rating tires can be completely trusted, the tire tread wear ratings guide is actually quite straightforward. To estimate a tread life based on treadwear ratings, you will need to multiply the number by 1000. Therefore, based on simple math, a 400-rated tire should last for 40,000 miles.Most passenger car tires feature treadwear grades between 300 and 600. However, the highest UTQG rating is 860 for a Hankook model. Still, tires with 500 treadwear are already good. Yet, this greatly depends on what type of tire you need, as high performance tires have lower ratings than touring ones.The treadwear marking demonstrates how long a tire can last. Treadwear has a range between 100-1000, where, for example, an 800 UTQG tire will last twice as long as a 400 UTQG tire. Tire treadwear performance is evaluated on a specific roadway course approximately 400 miles in length, which is established by the NHTSA.The Treadwear Grade is a comparative rating based on the tire’s wear rate when tested under controlled conditions on a specified government test track. It is not a projected mileage estimate but rather a relative measure.
What does 700 treadwear mean?
A tire that is treadwear rated 700 means that it far outlasted the tires against which it was tested. It is expected to last 7 times longer than a 100-UTQG treadwear-rated tire. A good UTQG treadwear rating is generally 300 or above, indicating the tire is expected to be worn three times, as well as the baseline tire set by the National Highway Traffic Safety Administration (NHTSA).The standard is set so that a rating of 100 is equal to 30,000 miles. The actual rating is a percentage of 30,000 miles. A tire rated at 200 has a projected tread life of 60,000 miles.Higher is better. The control tire has a treadwear grade of 100. So, if the tire being tested gets a 200 treadwear rating, that means it’s expected to take twice as long to wear out as the control tire.The higher the treadwear number is, the longer it should take for the tread to wear down. A control tire is assigned a grade of 100. Other tires are compared to the control tire. For example, a tire grade of 200 should wear twice as long as the control tire.
What is the maximum treadwear?
After careful examination, the tested tire is given a treadwear (UTQG) rating. The baseline rating starts at 100 and can exceed 800, with higher numbers indicating longer tread life. If a tyre is stored in optimal conditions, it will last for between 6 and 10 years, if it is not used. Under manufacturers’ guidance a tyre is only guaranteed to be safe for the first five years of its life, although if checked regularly for issues, some manufacturers admit that this can be extended up to 10 years.A tire with a 500 treadwear rating is expected to last approximately 50,000 miles under standard conditions. However, factors like driving style, road conditions, and vehicle type can affect actual mileage.Tyres will generally last an average of 40,000km, although this can vary widely depending on quality of road surfaces and your driving style. They should be checked annually once they reach the 5-year mark, and should be replaced every 10 years at the very least.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.Some tire experts contend that tires can last anywhere from six to ten years if they’re stored and cared for properly. We recommend replacing tires aged 6-10 years, no matter how much tread remains.
What does treadwear mean?
The test you’re trying to pass is all about road and vehicle safety. A treadwear grade is used to indicate the tire’s wear rate. The higher the number, the more time it will take to wear down the tread. The treadwear grade is a comparative rating based on the wear of a tire when tested carefully under controlled conditions. For example the useful tread on a tire graded 400 should last twice as long as a tire graded 200.TRACTION – AA, A, B and C: The traction grades from highest to lowest are AA, A, B and C and they represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete.Definition of tyre treadwear The results of these tests are represented by 3 figures. The higher the treadwear grade of the tyre, the longer it will last, and the more miles it will be able to travel. On the other hand, the lower the treadwear grade, the more quickly the tyre will wear out.
What is the minimum treadwear for tires?
While the minimum safe tire tread depth is 2/32″, consider replacing your tires at the 4/32″ mark, especially if you drive in rainy and snowy conditions. Good. Acceptable. Check tread depth monthly. Schedule tire replacement.What is the legal tyre limit of the tread depth ? The minimum tread depth is 1. This means that it is imperative to change your tyres once this limit has been reached to avoid compromising your safety and breaking the law. But it also means that it is premature to change your tyres before this threshold.You can expect around 1,000 miles out of your tyres if they’re down to 2 mm of tread.
How long will a 200 treadwear tire last?
The actual rating is a percentage of 30,000 miles. A tire rated at 200 has a projected tread life of 60,000 miles. On average, most tyres last between 40,000 to 80,000 kilometres. However, this estimate can change based on the factors mentioned earlier. High-performance tyres may have a shorter lifespan, while touring or all-season tyres tend to last longer.Its warranty is 80,000 miles, but Consumer Reports projects just 35,000. Tread-life testing some tires last much longer. Michelin was a standout. The three models we tested all met or exceeded their mileage warranty and came in with a projected tread life of 80,000 miles or more, said Rechtin.It is recommended that tyres be replaced after six years of use, even if they appear to be in good condition. The rubber used in the tyres will deteriorate over time, regardless of how much they are used. If do not know what the age of your tyres is, you can check the sidewall for something call the DOT code.Tire Age. Most tire manufacturers recommend replacing tires after 6 years, regardless of mileage. This is because rubber compounds can degrade over time, even if the tires appear unused. This degradation can lead to cracking, reduced flexibility, and increased risk of blowouts.
How long will 400 treadwear last?
While not even the best UTQG-rating tires can be completely trusted, the tire tread wear ratings guide is actually quite straightforward. To estimate a tread life based on treadwear ratings, you will need to multiply the number by 1000. Therefore, based on simple math, a 400-rated tire should last for 40,000 miles. The most obvious of which is how many miles they’ve been driven. Tire tread length generally wears down to replacement depth in between 36,000 to 45,000 miles driven. For the average driver this will take between 3 and 4 years. Other tire materials and components will wear out regardless of tread depth with age.Some tires are built to reflect a warranty of approximately 100,000 km while entry-level tires have a warranty of approximately 60,000 km. Summer tires should be replaced at 3mm tread depth and winter tires, also known as snow tires should be replaced at 4mm tread depth.
