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
conditions 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
sudden tire failure. Grades B and A
represent higher levels of
performance on the laboratory test
wheel than the minimum required by
law.
WARNING The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded.
Excessive speed, under-inflation,
over-inflation, or excessive loading,
either separately or in combination,
can cause heat build-up and possible
sudden tire failure. This may cause
loss of vehicle control resulting in an
accident.

Tire Terminology and
Definitions
Air pressure
The amount of air inside the tire
pressing outward on the tire. Air
pressure is expressed in lbs. per
square in. (psi) or kilopascal (kPa).Accessory weight
This means the combined weight of
optional accessories. Some examples
of optional accessories are gear,
power seats, and air conditioning.
Aspect ratio
The relationship of a tire’s height to
its width.
Belt
A rubber coated layer of cords that is
located between the plies and the
tread. Cords may be made from steel
or other reinforcing materials.
Bead
The tire bead contains steel wires
wrapped by steel cords that hold the
tire onto the rim.
Bias ply tire
A pneumatic tire in which the plies
are laid at alternate angles less than
90 degrees to the centerline of the
tread.
Cold tire pressure
The amount of air pressure in a tire,
measured in lbs. per square in. (psi) or
kilopascals (kPa) before a tire has
built up heat from driving.
Curb weight
This means the weight of a motor
vehicle with standard and optional
equipment including the maximum
capacity of fuel, oil and coolant, but
without passengers and cargo.
