Run-flat tire (RFT) or standard tire
( P. 759)
This vehicle can be equipped with eit her run-flat tires (RFT) or stan-
dard 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 main-
tains the air pressure.
Load limit at maximum cold tire inflation pressure ( P. 693)
Maximum cold tire in flation pressure ( P. 807)
This means the pressure to which a tire may be inflated.
Summer tires or all season tires ( P. 694)
An all season tire has “M+S” on the sidewall. A tire not marked
“M+S” is a summer tire.
“TEMPORARY USE ONLY” ( P. 769)
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.
