DOT and Tire Identification Number (TIN) ( P.552)
Location of treadwear indicators ( P.466)
Tire ply composition and materials
Plies are layers of rubber-coat ed parallel cords. Cords are the strands
which form the pl ies 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 t he tire and the tube maintains the air pres-
sure.
Load limit at maximum cold tire inflation pressure (P.466)
Maximum cold tire inflation pressure ( P.547)
This means the pressure to w hich a tire may be inflated.
