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 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
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 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 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 ...
Uniform Tire Quality Grading, commonly abbreviated as UTQG, is the term encompassing a set of standards for passenger car tires that measures a tire's treadwear, temperature resistance and traction.The UTQG was created by the National Highway Traffic Safety Administration in 1978, a branch of the United States Department of Transportation (DOT). All tires manufactured for sale in the United .....
Treadwear grades are an indication of a tire's relative wear rate. The higher the treadwear number is, the longer it should take for the tread to wear down. A control tire is assigned a grade of 100. Other tires are compared to the control tire. For example, a tire grade of 200 should wear twice as long as the control tire. Of current tires:

1) TREADWEAR RATINGS. Treadwear rating is designed to let the consumer know roughly how long the tire tread with last (in miles) before needing replacement. The tire is measured against a control tire which has a grade of 100. This means that a tire of treadwear rating of 200 should go twice as far before wearing out than a tire with treadwear ...
