4008-1. Specifications
For details, see “Uniform Tire Quality Grading” that follows.
Summer tires or all season tires (P.328)
An all season tire has “M+S” on the sidewall. A tire not marked “M+S” is a summer tire.
Compact spare tire
Tire size ( P.401)
DOT and Tire Identification Number (TIN) ( P.401)
Location of treadwear indicators ( P.328)
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.403)
Maximum cold tire inflation pressure ( P.403)
This means the pressure to which a tire may be inflated.
“TEMPORARY USE ONLY”
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.

■Traction AA, A, B, C
The traction grades, from highest to
lowest, are AA, A, B and C, and they
represent the tire’s ability to stop on
wet pavement as measured under con-
trolled conditions on specified govern-
ment test surfaces of asphalt and
concrete.
A tire marked C may have poor traction
performance.
Warning: The traction grade assigned to
this tire is based on braking (straight
ahead) traction tests and does not include
cornering (turning) traction.
■Temperature A, B, C
The temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudd
en tire failure.
Grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Fede ral Motor Vehicle
Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
Warning: The temperature grades for this
tire are established for a tire that is prop-
erly inflated and not overloaded.
Excessive speed, unde rinflation, or exces-
sive loading, either separately or in combi-
nation, can cause heat buildup and
possible tire failure.
Glossary of tire terminology
Tire related termMeaning
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 pressureThe maximum cold inflated pressure to which a tire may
be inflated, shown on the sidewall of the tire
Recommended inflation pres-
sureCold tire inflation pressure recommended by a manufac-
turer
Accessory weight
The combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power
steering, power brakes, powe r windows, power seats,
radio and heater, to the extent that these items are avail-
able as factory-installed equi pment (whether installed or
not)
