Tread wear
The tread wear grad e is a com parative rating
based on the wear rate of the tire when tested
und er controlled cond itions on a specified
governm ent test cou rse. For exam ple, a tire
grad ed 150 would wear one and one-half (1 1/ 2)
tim es as well on the governm ent cou rse as a tire
grad ed 100. The relative perform ance of tires
depend s upon the actu al cond itions of their use,
how ever, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteristics
and climate.
Traction A B C
The traction grad es, from highest to low est, are
A, B, and C, and they rep resent the tire’s ability
to stop on wet pavem ent as measu red und er
controlled cond itions on specified governm ent
test surfaces of asp halt and concrete. A tire
marked C may have poor traction perform ance.
Warning: The traction grad e assigned to this tire
is based on braking (straightahead ) traction tests
and does not inclu de cornering (tu rning)
traction.
Tem peratu re A B C
The tem peratu re grad es are A (the highest), B,
and C, rep resenting the tire’s resistance to the
generation of heat and its ability to dissip ate
heat when tested und er controlled cond itions on
a specified ind oor laboratory test wheel.
Sustained high tem peratu re can cau se the
material of the tire to degenerate and red uce tire
life, and excessive tem peratu re can lead to
sudden tire failu re. The grad e C corresp ond s to
a level of perform ance which all passenger car
tires must meet und er the Federal Motor Vehicle
Safety Stand ard No. 109. Grad es B and A
