The specific grade rating assigned by the tire's manufacturer in each category is shown on the sidewall of the tires on your vehicle. Treadwear The Treadwear grade is a comparative rating, based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one-half times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices, and differences in road characteristics and climate. Traction Grades The Traction grades, from highest to lowest, are AA, A, B, and C. These grades represent the tire's ability to stop on wet pavement, as measured under controlled conditions on specified government test surfaces of asphalt and All passenger car tires must conform to Federal safety concrete. A tire marked C may have poor traction perforrequirements in addition to these grades. mance. 9
