Run-flat tire (RFT) or standard tire ( P. 515)
This vehicle can be equipped with either run-flat tires (RFT) or standard tires. An
“RFT” or “DSST” mark is molded on the sidewall of the run-flat tire.
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.
