Pre-Travel Information
Recommended Tire Pressure
& Load Limits
The major causes of tire failure are under-inflated tires
and overloaded vehicles. Tire information placards and
vehicle certification labels give important information on tires
and load limits, including:
• Recommended Tire Size
• Recommended Tire Inflation Pressure
• Cargo Weight
(the maximum cargo weight the RV is designed to carry)
• Front and Rear Gross Axle Weight Ratings (GAWR)
(the maximum weight the axle system is designed to
carry)
For the label locations and more detailed information,
See page 51, Weight Labels.
Understanding Tire Pressure
& Load Limits
Load Limits are determined by the tire size and the greatest
amount of weight each tire can safely carry.
Tire Pressure is the amount of air pressure a tire requires to
be properly inflated. It is measured in pounds per square inch
(PSI). Tire pressure aects your RV's overall performance and
provides the load-carrying capacity.
The proper tire pressure for your vehicle is referred to as the
“cold inflation pressure.” You will also find this number on the
vehicle information placard expressed in both PSI and kilo-
pascals (KPA), the metric measurement used internationally.
It is dicult to obtain the recommended tire pressure when the
tires are not cold.
See the next page, Checking Tire Pressure.
Keep tires properly
inflated. A tire that is run
long distances or at high
speeds while seriously
under-inflated will overheat
to the point where the
tire may lose air suddenly
and/or catch fire, possibly
resulting in damage to the
vehicle and its contents
and/or personal injury.
Exceeding the established
weight ratings for the axles,
running gear, tires and
wheels can lead to
failure that can aect motor
vehicle safety and lead
to property damage or
damage to the RV.
