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.
Just so, how many miles does a tire last?
50,000 miles
A tire rated at 200 has a projected tread life of 60,000 miles.
