A tire treadwear rating refers to the amount of time the treads on a tire should last in specific conditions. Tire manufacturers indicate treadwear rating on their tires using a set of numbers between 100 and 700. These numbers indicate how long tire treads will remain safe and perform at their high
The treadwear rating of a tire is the number listed on a tire's sidewall that states how well the tire wears compared to other tires. If a tire has a 200 rating, it wears twice as long as a tire with a rating of 100.
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.
A treadwear rating chart is a matrix of numerical grades assigned to a tire based on the uniform tire quality grade standards. Tire manufacturers assign a treadwear rating to each tire model, not as an absolute test of strength but as a comparison between tire models for a given brand.
Safercar.gov provides a comprehensive treadwear rating chart for most of the tires used in the United States. The rating chart is based on the Uniform Tire Quality Grading System developed by the U.S. Department of Transportation. Tires with high treadwear ratings last longer.
A tire with a "600" treadwear rating might not last exactly 3 times as long as a tire with a "200" treadwear rating, but it's a safe assumption that the "600" rated tire will be longer-lasting. If you're shopping for a high-mileage set of tires, a low treadwear rating is a red flag and an indication that the tire might fall short of your ...
On Tread Life …While not an exact science, these UTQG ratings can offer some insight into a tire. Let’s look at the UTQG’s treadwear ratings (e.g. 700 AA A) since it is one that consumers focus on. In theory, the larger the number, the longer the tread life.

For example, a tire with a treadwear rating of 700 may last approximately 70,000 miles. There is no real science supporting this “rule.” Unfortunately, the rating that is of the most interest to consumers is the one that is the least consistent. Originally intended to be assigned in a purely scientific manner, the UTQG treadwear rating has ...
The CMT tire has an established grade of 100 and a calculated longevity of 30,000 miles. A tire that scores 200 can be expected to wear twice as well as the CMT tire, but its mileage won't necessarily be double. It's not uncommon for tires with scores ranging from 300 to 700 to both last about 60,000 real-world miles.
