Treadwear & Traction
All tires have a treadwear “grade”, a rating system to demonstrate the life of that tire’s tread under controlled conditions. A tire with the treadwear grade of 300 should last twice as long as a grade 150. Grading systems are specific to tire brands, meaning a 200 grade in one brand may not be exactly equivalent to a 200 grade in a different brand.
Likewise, there are grades to represent a tire’s traction, that is the ability to stop. Grades ranked from highest to lowest are as such; “AA”, “A”, “B” and “C”. Naturally, “AA” tires are expected to perform more efficiently on wet and snowy surfaces.
Treadwear Rating (UTQG)
Tire sidewall markings, what they mean...
Other branding lists the types of materials used internally to reinforce the rubber, along with the tire's maximum inflation pressures and loads. Other markings confirm that the manufacturer certifies that the tire meets various tire industry safety standards and measures up to governmental regulations.
