Tire size(→ P. 760)
DOT and Tire Identification Number (TIN) (→ P. 760)
Location of treadwear indicators (→ P. 618)
Tire ply composition and materials
Plies are layers of rubber-coated parallel cords. Cords are the strands
which form the plies in a tire.
Summer tires or all season tires (→ P. 623)
An all season tire has “M+S” on the sidewall. A tire not marked “M+S”
is a summer 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. 622)
Maximum cold tire inflation pressure (→ P. 752)
This means the pressure to which a tire may be inflated.
Uniform tire quality grading
For details, see “Uniform Tire Quality Grading” that follows.
“TEMPORARY USE ONLY”
A compact spare tire is identified by the phrase “TEMPORARY USE
ONLY” molded on its sidewall. This tire is designed for temporary
emergency use only.
