Tire size (P.471)
Run-flat tire (RFT) or standard tire ( P.439)
This vehicle can be equipped with either run-flat tires (RFT) or standard tires. A
mark is molded on the sidewall of the run-flat tire.
DOT and Tire Identification Number (TIN) ( P.471)
Location of treadwear indicators ( P.392)
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.393)
Maximum cold tire inflation pressure ( P.464)
This means the pressure to which a tire may be inflated.
