Tire traction is used to gauge the ability of a tire to perform on dry and wet surfaces. Traction can vary based on a tire's tread patterns and compounds. Each tire has a tire traction rating that grades how well a new tire stops on wet roads when properly inflated. Each result is basedon controlled tests and graded with AA, A, B or C ratings. Traction ratings with a AA grade means a tire has the best possible traction while a C grade denotes the lowest.
