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 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 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. To understand how treadwear ratings vary and for basic real world reference points, consider that standard touring all-season tires engineered for high mileage can have ...
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.
The amount of tread on a tire is critical in determining how well it will vacate water to maintain contact with the road in the rain. If your tires wear out quickly, your safety may be at risk.
