dif fere nces in road characteristics and climate
conditions.

DANG ER Risk of accident due toinade‐
qu ate traction
The traction grade assigned tothis tire is
based on stra ight-ahead braking traction
te sts, and does not include either accelera‐

Avoid wheelspin. The traction grades – from highest
tolowest –
are AA, A,B and C. Those grades represent the
tire's ability tostop on wet pa vement as meas‐

WARNING Risk of accident from tire
ove rheating and tire failure
The temp erature grade forth is tire is es tab‐
lished for a tire that is proper ly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately
or in combination, can cause excessive heat
build-up and possible tire failure. #
Obser vethere commended tire pres‐
su res and regularly check the tire pres‐ sure of all tires including
the spare
wheel. #
Adjust the tire pressure as necessar y. The
temp erature grades are A (the highest), B
and C. They represent the tire's resis tance tothe
ge neration of heat and its ability todissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel. Sus‐
ta ined high temp erature can cause the material
of the tire todegenerate and reduce tire life, and
exc essive temp erature can lead tosudden tire
fa ilure. Grade C cor responds toa le vel of per‐
