RC F_U Tire size (  P. 560)
DOT and Tire Identification Number (TIN) (  P. 559)
Location of trea dwear indicators (  P. 412)
Tire ply composition and materials Plies are layers of rubber-c oated 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. 564)
Maximum cold tire inflation pressure (  P. 564)This means the pressure to which a tire may be inflated.
Uniform tire quality grading For details, see “Uniform Tire Quality Grading” that follows.
Summer tires or all season tires (  P. 416)An all season tire has “M+S” on the side wall. A tire not marked “M+S” is a summer
tire.
“TEMPORARY USE ONLY” A compact spare tire is identified by the phrase “TEMPORARY USE ONLY” molded
on its sidewall. This tire is design ed for temporary emergency use only.1
