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 UTQG 720 AA mean?
A UTQG rating is made up of a three-digit number and two letters or letter groups. For example, a tire might have a 720 A A rating. The first letter or group of letters is the traction rating. The best grade is AA, followed by A, B and C. The better the grade, the better the tire will stop in wet conditions.
What does UTQG 300 AA A mean?
Uniform Tire Quality Grade (UTQG) Standards | Tire Rack …that the tire tread would last as long as the test tire, 200 would indicate the tread would last twice as long, 300 would indicate three times as long, etc.
What does 500 AA stand for on a 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.
How do I read my UTQG rating?
The Course Monitoring Tire is assigned a grade and the test tire receives a grade indicating its relative treadwear. A grade of 100 would indicate that the tire tread would last as long as the test tire, 200 would indicate the tread would last twice as long, 300 would indicate three times as long, etc.
How many miles is a 600 treadwear rating?
That said, the most accurate indicator for how many miles a tire will last may be its mileage warranty. Unlike a treadwear grade, a warranty is the manufacturer putting their money where their mouth is. A tire rated 600 AA with a 70,000 mile warranty is quite likely to live up to it.
How long will 400 treadwear last?
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.
Is UTQG 820 AB good?
Here’s what’s important: The higher the tread wear grade, the longer a tire will last—according to the company that made the tire. 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.
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.
What does UTQG stand for?
“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.
What is an UTQG treadwear rating?

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 is tire temperature rating?
Tire temperature rating grades a correctly inflated tire’s ability to resist and properly disperse heat. A tire temperature grade ranges from A to C, with C being the lowest possible score under federal regulations.
What do tire ratings mean?
