Tire ply composition and materials
Plies are layers of rubber-coated parallel cords. Cords are the strands
which form the p lies in a tire.
Uniform tire quality grading
For details, see “Uniform Tire Q uality Grading” that follows.
Load limit at maximum cold tire inflation pressure ( P. 619)
Maximum cold tire inflation pressure ( P. 619)
This means the press ure to which a tire may be inflated.
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 insi de the tire and the tube mainta ins the air
pressure.
Radial tires or bias-ply tires
A radial tire has “RADIAL” on the sidewall. A tire not marked “ RADIAL”
is a bias-ply tire.
