A tire with a treadwear rating of 320 should last for approximately 40,000 miles. This is a lower-middle level treadwear rating. Tires with a high-end rating of over 500 should deliver approximately 80,000 miles.

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.
