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 filled in 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. 372)
Maximum cold tire inflation pressure ( →P. 496)
This means the pressure to which a tire may be inflated.
Summer tire or all season tire ( →P. 372)
An all season tire has “M+S” on the sidewall. A tire not marked
“M+S” is a summer tire.
“TEMPORARY USE ONLY” ( →P. 458)
A compact spare tire is identified by the phrase “TEMPORARY
USE ONLY” molded into its sidewall. This tire is designed for tem-
porary emergency use only.

Warning: The temperature grades of a tire assume that it is properly
inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either sepa-
rately or in combination, can cause heat buildup and possible tire fail-
ure.

Cold tire inflation
pressure Tire pressure when the vehicle has been
parked for three hours or more, or has not
been driven more than 1 mile or 1.5 km under
that condition
Maximum inflation
pressure The maximum cold inflated pressure to which a
tire may be inflated, shown on the sidewall of
the tire

Accessory weight The combined weight (in excess of those stan-
dard items which may be replaced) of auto-
matic transmission, power steering, power
brakes, power windows, power seats, radio
and heater, to the extent that these items are
available as factory-installed equipment
(whether installed or not)
Curb weight The weight of a motor vehicle with standard
equipment, including the maximum capacity of
fuel, oil and coolant, and if so equipped, air
conditioning and additional weight optional
engine
Maximum loaded
vehicle weight The sum of:
(a) Curb weight
(b) Accessory weight
(c) Vehicle capacity weight
(d) Production options weight

Light truck (LT) tire A tire designated by its manufacturer as prima-
rily intended for use on lightweight trucks or
multipurpose passenger vehicles
Load rating The maximum load that a tire is rated to carry
for a given inflation pressure
Maximum load rating The load rating for a tire at the maximum per-
missible inflation pressure for that tire
Maximum permissible

a tire may be inflated
