GVWR (Gross Vehicl eWeight Rating)
The GVWR is the maximu mpermitted gross
weight of the full yladen vehicle (weight of the

Rthe weight of the accessories
Rthe loadl imit
Rthe weight of the factory installed optional
equipment
Kilopascal (kPa)

equivalent of 1psi.A nother tire pressure unit is
bar. 100 kilopascals (kPa) are the equivalent of
1b ar.
Load index

index can be stamped onto the sidewal lofthe
tire. It specifies the load-bearing capacity of the
tire more precisely.

percent.
Tire pressure
Pressure inside the tire applying an outward
force to every square inch of the tire's surface.
Tire pressure is specified in pounds per square
inch (psi), in kilopascal (kPa) or in bar. Tire pres-
sure shoul donly be corrected when the tires are
cold.
Col dtire pressure
The tires are cold:
Rif the vehicle has been parked for at least
three hours withou tdirect sunlight on the
