Tire information
Ti r e s i z e (  P. 5 76 )
DOT and Tire Identification Number (TIN) (  P. 5 7 5 )
Location of treadwear indicators (  P. 4 8 6 )
Tire ply composition and materials Plies are layers of rubber-coated parallel co rds. Cords are the strands which form the
plies in a tire.
Radial tires or bias-ply tires A radial tire has “RADIAL” on the sidewall. A tire not marked “RADIAL” is a bias-ply
tire.
TUBELESS or TUBE TYPE A tubeless tire does not have a tube and air is directly put into the tire. A tube type tire
has a tube inside the tire and the tube maintains the air pressure.
Load limit at maximum cold tire inflation pressure (  P. 5 8 0 )
Maximum cold tire inflation pressure (  P. 5 8 0 )This means the pressure to which a tire may be inflated.
Uniform tire quality grading For details, see “Uniform Tire Quality Grading” that follows.
Summer tires or all season tires (  P. 4 9 0 )An all season tire has “M+S” on the sidewall. A tire not marked “M+S” is a summer
tire.Ty p i c a l t i r e s y m b o l s

Vehicle specifications ■
Temperature A, B, C
The temperature grades are A (the highes t), B, and C, representing the tire’s
resistance to the generation of heat and its ability to dissipate heat when
tested under controlled conditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead to sudden tire failure.
Grade C corresponds to a level of perfor mance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of performance on the laboratory test
wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is properly inflated and
not overloaded.
Excessive speed, underinflation, or excessiv e loading, either separately or in com-
bination, can cause heat buildup and possible tire failure.
