Quality grading information
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETYREQUIREMENTS IN ADDITION TO THESEGRADES Quality grades can be found, where appli- cable, on the tire sidewall between thetread shoulder and maximum sectionwidth. For example: Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating based on the wear rate of the tire when tes-ted under controlled conditions on a specifiedgovernment test course. For example, a tiregraded 150 would wear one and one half(1 1/2) times as well on the governmentcourse as a tire graded 100. The relative per-formance of tires depends upon the actualconditions of their use, however, and manydepart significantly from the norm due to var-iation in driving habits, maintenance practicesand differences in road characteristics andclimate.
TRACTIONThe traction grades, from highest to lowest,are AA, A, B, and C, as measured under con-trolled conditions on specified governmenttest surfaces of asphalt and concrete. A tiremarked C may have poor traction perform-ance. The traction grade assigned to this tireis based on braking (straight-ahead) tractiontests and is not a measure of cornering (turn-ing) traction.
WARNING
The traction grade assigned to this tire is based on braking (straight-ahead) tractiontests and is not a measure of cornering(turning) traction.
TEMPERATUREThe temperature grades are A (the highest), B, and C, representing the tire's resistance tothe generation of heat and its ability to dissi-pate heat when tested under controlled con-ditions on a specified indoor laboratory testwheel. Sustained high temperature can causethe material of the tire to degenerate andreduce tire life, and excessive temperaturecan lead to sudden tire failure. The grade Ccorresponds to a minimum level of perform-ance that all passenger vehicle tires mustmeet under the Federal Motor Safety Stand-ard No. 109. Grades B and A represent higherlevels of performance on the laboratory testwheel than the minimum required by law.
WARNING
The temperature grade for this tire is established for a tire that is properly infla-ted and not overloaded. Excessive speed,under-inflation, or excessive loading, eitherseparately or in combination, can causeheat buildup and tire failure.
