Editor's note: All tires are listed in order of treadwear rating first, then by alphanumeric order. All tires and sizes were available for retail sale in the U.S. market as of June 15, 2010.
The government has established the Uniform Tire Quality Grading (UTQG) system to help consumers choose their tires. The UTQG is a relative comparison system, and is not a safety rating, nor a guarantee that a tire will last for a specific number of miles. Under the UTQG system, "treadwear" is a comparative rating based on the wear of a tire when tested under laboratory test conditions. Under this scheme, a tire graded "400" should last twice as long as a tire graded "200." Nevertheless, another tire manufacturer may grade a comparable design "300," so a grade of "150" would last just half as long under its grading scheme. It is also common with R-compound tires for a manufacturer to assign a treadwear rating that is conservative for that tire, whereby a tire that could qualify for a "100" rating is actually given a "00" rating. (Theoretically at least, a tire with a "00" rating should last zero miles, but contrary to common belief, they do not disintegrate upon mounting!) The "Traction" rating is how well a tire brakes in a straight line on wet pavement. In the case of R-compound DOT-legal tires or UHP tires, which are seldom driven in wet conditions, a "C" rating means it passes minimum requirements for wet weather-the rating is not indicative of dry traction, nor is it an indication of turning or handling performance. The "Temperature" rating is a measure of how hot the tires run, not an indication of grip or safety.
