MANDALAY
It is the air pressure that enables a tire to support the load, so proper inflation is critical.
Since motorhomes can be configured and loaded in many ways, air pressures must be
determined from actual loads (determined by weighing) and taken from the load and inflation
tables provided by the tire manufacturer. These air pressures may differ from those found on
the certification label. However, they should never exceed the tire limitation for load or air
pressure. If you discover that your tires cannot support the actual weights, the load will need to
be lightened.
Preventing Tire Damage
• Slow down if you have to go over a pothole or other object in the road.
• Do not run over curbs or other foreign objects in the roadway, and try not to strike the
curb when parking.
Tire Safety Checklist
• Check tire pressure regularly (at least once a month).
• Inspect tires for uneven wear patterns on the tread, cracks, foreign objects, or other
signs of wear or trauma.
• Remove bits of glass and foreign objects wedged in the tread.
• Make sure your tire valves have valve caps.
• Check tire pressure before going on a long trip.
• Do not overload your motorhome. Check the Tire Information and Loading Placard or
Chassis Manual for the maximum recommended load for the motorhome.
1. Locate the statement “The combined weight of occupants and cargo should never
exceed XXX lbs on the motorhome placard.”
2. Determine the combined weight of the driver and passengers that will be riding in the
motorhome.
3. Subtract the combined weight of the driver and passengers from the XXX kilograms or
XXX pounds.
4. The resulting figure equals the available amount of cargo and luggage capacity. For
example, if the “XXX” amount equals 1400 lbs. and there will be five 150 lb.
passengers in the motorhome, the amount of available cargo and luggage capacity is
650 lbs. (1400-750 (5 x 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle.
That weight may not safely exceed the available cargo and luggage capacity
calculated in Step #4.
6. If the motorhome will be towing a trailer, load from the trailer will be transferred to the
motorhome. Consult this manual to determine how this reduces the available cargo and
luggage capacity of the motorhome.
