Tire ply composition and materials
Plies are layers of rubber-coated parallel cords. Cords are the
strands which form the plies in a tire.
Uniform tire quality grading
For details, see “Uniform Tire Quality Grading” that follows.
Load limit at maximum cold tire inflation pressure ( →P. 348)
Maximum cold tire inflation pressure ( →P. 348)
This means the pressure to which a tire may be inflalted.
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.

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.
