to tread quality, tire traction and temperature char-
acteristics. The quality grading assessment is
made by the manufacturer in accordance with test
speci cations of the U.S. government. The quality
grade of a tire is imprinted on the sidewall of the
tire.
R R ecommended tir ecommended tire pr e pressur essure: e: the recommended
tire pressure is the pressure speci ed for the tires
installed to the vehicle at the factory.
The Tire and Loading Information placard contains
the recommended tire pressures for cold tires, the
maximum permissible load and the maximum per-
missible vehicle speed.
The tire pressure table contains the recommended
tire pressures for cold tires under various operat-
ing conditions, i.e. load and/or speed of the vehi-
cle.

GAWR (Gr GA WR (Gross Axle W oss Axle Weight R eight Rating): ating): GAWR is the
axle load. The actual load on an axle must never
exceed the Gross Axle Weight Rating. You can nd
the Gross Axle Weight Rating on the B-pillar on the
driver's side.
Speed rating: Speed r ating: the speed rating is part of the tire
identi cation. It speci es the speed range for
which a tire is approved.
G G VW (Gr VW (Gross V oss Vehicle W ehicle Weight): eight): the Gross Vehicle
Weight includes the weight of the vehicle including
fuel, tools, the spare wheel, accessories installed,
occupants, luggage and the trailer drawbar nose-
weight if applicable. The Gross Vehicle Weight
must never exceed the Gross Vehicle Weight Rat-
ing (GVWR) as speci ed on the vehicle identi ca-
tion plate on the B-pillar on the driver's side.
G G VWR (Gr VWR (Gross V oss Vehicle W ehicle Weight R eight Rating):
the maximum permitted gross weight of the fully
laden vehicle (weight of the vehicle including all
accessories, occupants, fuel, luggage and the
trailer drawbar noseweight if applicable). The
Gross Vehicle Weight Rating is speci ed on the
vehicle identi cation plate on the B-pillar on the
driver's side.

equipment.
Kilopascal (kPa): a): metric unit for tire pressure. Kilopascal (kP
6.9 kPa are the equivalent of 1 psi. Another unit
for tire pressure is bar. 100 kilopascals (kPa) are
the equivalent of 1 bar.

equipment including the maximum capacity of fuel,
oil and coolant. It also includes the air-conditioning
system and optional equipment if these are instal-
led on the vehicle, but does not include passen-
