What does treadwear 520 mean on a tire?
If a tire is rated 100, it is expected to last as long as the test tire. In the above example, the treadwear rating is 520, so a tire tech may estimate the tread life of that tire at around 52,000 miles.
What does UTQG 500 AB mean?
“UTQG” stands for “Uniform Tire Quality Grading”. A system developed by the Department of Transportation, which helps consumers compare and rate tires on tread wear, traction, and temperature. Example: a tire with a UTQG of 400 AB. Traction and Temperature ratings are rated (A) superior, (B) good and (C) average.
Is 540 a good treadwear rating?
TECH CENTER – TIRE TREADWEAR A treadwear rating generally falls between 60 and 540. A tire with a treadwear rating of 400, for example, is likely to last twice as long as a tire rated at 200.
Is a higher UTQG better?
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.
What speed rating is W?
168 mph
A relatively new addition to the speed rating chart, tires with speed rating “W” can achieve a maximum sustained speed of 168 mph (270 kph).
How long will a 200 treadwear tire last?
60,000 miles
A tire rated at 200 has a projected tread life of 60,000 miles. A tire rated at 50 has a projected tread life of 15,000 miles.
Is 640 treadwear good?
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.
What is the UTQG and how does it work?
The UTQG makes it possible to compare tires based on a standardized rating of treadwear, traction, and temperature resistance. The grade for each of these can be found on the side of your tire. Winter tires and certain light truck tires are not graded.
What does UTQG treadwear grade mean?
The UTQG treadwear grade indicates how long your tire tread will last in relation to other tires. For instance, a tire with a grade of 400 should last twice as long as a tire with a grade of 200.
What is the uniform tire quality grading system (UTQG)?
To help consumers evaluate their tires, the U.S. National Highway Traffic Safety Administration (NHTSA) created the Uniform Tire Quality Grading System (UTQG). The UTQG makes it possible to compare tires based on a standardized rating of treadwear, traction, and temperature resistance.
