What does treadwear grade mean?

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. Traction and temperature scores: Those scores denote a tire’s wet-stopping ability and temperature resistance.

What is a good treadwear grade?

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 does a treadwear rating of 500 mean?

This number designation is designed to give you a picture of the durability or life you can expect from your tire. This rating is based off a 100-tread wear control tire. 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.

What does a treadwear rating of 400 mean?

“UTQG” stands for “Uniform Tire Quality Grading”. 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.

How does treadwear rating work?

Treadwear. The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test track. In theory, this means that a tire with a 200 grade will wear twice the distance as a tire with a 100 grade.

How many miles is a 560 treadwear rating?

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.

Is a higher treadwear number better?

The treadwear grade is designed to give you a picture of the durability or life you can expect from your tire. What you need to know about the treadwear grade is this: The higher the treadwear number, the longer it’ll take the tread to wear down. Higher is better. The control tire has a treadwear grade of 100.

Does Utqg matter?

Uniform Tire Quality Grade (UTQG) is a required marking on the tire sidewall intended to provide a standardized metric that helps consumers purchase tires based on relative treadwear, traction and temperature capabilities. Since most tires last longer than this, interpretation of the data can vary.

Is 480 treadwear good?

The bottom line on the treadwear ratings is that they are relative to the other tires a particular manufacturer makes. So a 480 in Goodyear’s line is different than a 480 in Pirelli’s line. Or Kuhmo’s line. But generally when you hit the 400’s and above, you’re into pretty durable tires.

Does UTQG matter?

Which traction grade signifies the best traction?

AA
A traction grade tells you how well your tire can stop in wet conditions. The highest traction grade is AA, followed by A, B, and C. Tires with an ‘AA’ traction rating should stop at a much shorter distance than a tire with a ‘C’ rating.

How is treadwear calculated?

Find the Treadwear Rating on your worn set of tires and the mileage you put on those tires. Divide the total mileage you put on your old tires by the Treadwear Rating of those tires. Multiply the answer by the Treadwear Rating on the new set of tires. This will give you an estimate of how long the new tires will last.
