Treadwear rating number can be used to compare treadwear longevity between tires. Note that tire performance depends on your driving manner and actual conditions. Hence, do not be surprised if you get more or less mileage than the rating.

Traction ratings are based on a 40mph test where the brakes are locked on wet asphalt or concrete surfaces. Note that this rating does not indicate the tire’s ability to resist hydroplaning, and do not apply to cornering traction.

Temperature ratings are determined by running tires on an indoor roadwheel test under specified conditions, increasing speed until the tires fails. Tires with an A rating must withstand at least 114mph, B at least 99mph, and C at least 85mph. These measurements indicate the tire's ability to sustain high temperatures which can cause a tire to wear away quickly resulting in sudden tire failure.
