GVWR Gross Vehicle Wei ht Ratin
The G WR is the maximum permitted gross
weight of the fully laden vehicle (weight of the

The maximum weight is the sum of:
the curb weight of the vehicle
R
the weight of the accessories
R
the load limit

equipment
ilo ascal Pa
Metric unit for tire pressure. 6. kPa corre-
sponds to 1 psi. Another unit for tire pressure is
bar. 100 kilopascals (kPa) are the equivalent of
1 bar.

ward force to each square inch of the tire's sur-
face. The tire pressure is specified in pounds per
square inch (psi), in kilopascal (kPa) or in bar.
The tire pressure should only be corrected when
the tires are cold.
old tire ressure
The tires are cold:
if the vehicle has been parked with the tires
R
out of direct sunlight for at least three hours
and
