with test specifications of theU. S. go vernment.
The quality grade of a tire is imprinted on the

The Tire and Loading In form ation placard con‐
ta ins there commended tire pressures for cold
tires, the maximum permissible load and the

re ga rdless of whe ther it is actually ins talled on
th eve hicle or not.
Rim: the part of the wheel on which the tire is
ins talled.
GA WR (Gross Axle Weight Rating): GAWR is the
gross axle weight rating. The actual load on an
axle mu stneverexc eed the Gross Axle Weight Ra

on the B-pillar on the driver's side.
Speed rating: the speed rating is pa rtof the tire
identification. It specifies the speed range for
which a tire is appr oved.
GV W (Gross Vehicle Weight): the Gross Vehicle
We ight includes thewe ight of theve hicle includ‐
ing fuel, tools, the spare wheel, accessories
ins talled, occupants, luggage and the trailer
dr aw bar nose weight if applicable. The Gross Vehi‐
cle Weight must ne verexc eed the Gross Vehicle

GV WR (Gross Vehicle Weight Rating): the
GV WR is the maximum permitted gross weight of
th e fully laden vehicle (weight of theve hicle
including all accessories, occupants, fuel, lug‐

cable). The Gross Vehicle Weight Rating is speci‐
fi ed on theve hicle identification plate on the B-

Aspect
ratio: relationship between tire height
and tire width in percent.
Ti re pressure: pressure inside the tire applying
an outward forc eto eve rysquare inch of the
tire's su rface. The tire pressure is specified in
pounds per square inch (psi), in kilopascal (kPa)
or in bar. The tire pressure should only be cor rec‐
te d when the tires are cold.
Ti re pressure on cold tires: the tires are cold
when theve hicle has been par ked with the tires
out of direct sunlight for at least thre e hours and
th eve hicle has been driven less than 1 mile
(1.6 km).
Ti re contact sur face: the part of the tire that
comes into con tact wi th thero ad.
Ti re bead: the purpose of the tire bead is to
ensure that the tire sits securely on the wheel

to preve ntthe tire from changing length on the
wheel rim.
Side wall:the part of the tire between the tread
and the tire bead.
Special equipment weight: the combined

are not included in the curb weight and the
we ight of the accessories.
TIN (Tire Identification Number): a unique iden‐
tification number which can be used bya tire
manufacturer toidentify tires, forex ample for a
product recall, and thus identify the pur chasers.
The TIN is made up of the manufacturer identifi‐
cation code, tire size, tire type code and the man‐
ufacturing date.
Load-bearing index: the load-bearing index (also
load index) is a code that con tains the maximum
load-bearing capacity of a tire.
Tr action: traction is there sult of friction between
