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.
The UTQG treadwear number is one of the trickiest things on a tire. It is supposed to measure treadwear, but every brand sets its own numbers, and they are not easily compared. Generally, the lower the treadwear, the more grip the tire has, but even then it is not a reliable measurement. As…
The Truth About Tire Treadwear ... A government-required number that indicates a tire’s expected wear. A grade of 300 denotes a tire that will wear three times as well as a tire graded 100. But ...
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:
The UTQG (Uniform Tire Quality Grade) treadwear rating, also known as a treadwear grade, is a number stamped on the tire sidewall that relates to expected tire life. In basic terms, and in the spirit of the concept, the higher the UTQG treadwear rating, the greater the tire life.
The treadwear rating scale starts with the number 100. Tires with this rating might be suitable for light driving or seasonal driving, as they wear more quickly than tires with higher ratings. The scale increases by increments of 50, and each increase indicates a longer lifespan.
