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.

Maximum cold tire inflation pressure (P. 525)
This means the pressure to which a tire may be inflated.
Load limit at maximum cold tire inflation pressure (P. 525)
Summer tire or all season tire (P. 414)
An all season tire has “M+S” on the sidewall. A tire not marked
“M+S” is a summer tire.
