Tire size ( P. 7 9 8 )
DOT and Tire Identification Number (TIN) ( P. 7 9 7 )
Location of treadwear indicators ( P. 6 5 1 )
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 put into the tire. A tube type
tire has a tube inside the tire and the tube maintains the air pressure.
Load limit at maximum cold tire inflation pressure ( P. 8 0 2 )
Maximum cold tire inflation pressure ( P. 8 0 2 )
This means the pressure to which a tire may be inflated.
Uniform tire quality grading
For details, see “Uniform Tire Quality Grading” that follows.
Summer tires or all season tires ( P. 6 5 6 )
An all season tire has “M+S” on the side wall. A tire not marked “M+S” is a summer
