Maximum Load Rating
The Maximum Load Rating indicates the maximum load in
kilograms and pounds that can be carried by the tire.
Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that should
ever be put in the tire under normal driving conditions.
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 affects your RV’s overall performance and
provides the load-carrying capacity.
On the
Tire and Loading Information Label, t
he proper tire
pressure for your vehicle is listed as Cold Tire Pressure .
You will find this number expressed in both PSI and kilo-pascals
(KPA), the metric measurement used internationally.
It is difficult to obtain the recommended tire pressure when
the tires are not cold.
See the
next page
, Checking Tire Pressure.
Because tires are
designed to be
used on more than
one type of vehicle,
tire manufacturers list the
“maximum permissible
inflation pressure” on the
tire sidewall. This number
is the greatest amount of
air pressure that should
ever be put in the tire under
normal driving conditions.
