Tire information
Tire size ( P. 521)
DOT and Tire Identification Number (TIN) ( P. 521)
Location of treadwear indicators ( P. 417)
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. 525)
Maximum cold tire inflation pressure ( P. 525)
This means the pressure 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 inside the tire and the tube maintains 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.
Summer tire or all season tire ( P. 421)
An all season tire has “M+S” on the sidewall. A tire not marked “M+S”
is a summer tire.
