Vehicle specifications
Tire ply composition and materials
Plies are layers of rubber-coated parallel cords. 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 filled in the
tire. A tube type tire has a tube inside the tire and the tube main-
tains the air pressure.
Load limit at maximum cold tire inflation pressure (P. 355)
Maximum cold tire inflation pressure (P. 454)
This means the pressure to which a tire may be inflated.
Summer tires or all season tires (P. 356)
An all season tire has “M+S” on the sidewall. A tire not marked
“M+S” is a summer tire.
“TEMPORARY USE ONLY” (P. 420)
A compact spare tire is identified by the phrase “TEMPORARY USE
ONLY” molded into its sidewall. This tire is designed for temporary
emergency use only.

466 6-1. Specifications
Warning: The temperature grades for this tire are established for a
tire that is properly inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either sepa-
rately or in combination, can cause heat buildup and possible tire fail-
ure.
