Consequently, how many miles is a 400 treadwear rating?
The first portion of the rating is a 2 – or 3-digit number that represents relative treadwear, or how long the tire's tread is expected to last against the standard test tire. The test track they use is a 400-mile loop for a total of 7,200 miles. If a tire is rated 100, it is expected to last as long as the test tire.
Additionally, what is a good treadwear rating? 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.
Just so, how many miles does a tire last?
How long will 200 treadwear last?
A tire rated at 200 has a projected tread life of 60,000 miles.
