The wheel/tire assemblies used on your coach are heavy-duty truck-type. They are heavy and may be diffi cult to handle. If
at all possible, changes should be accomplished by a service station equipped to handle truck equipment. However, if a
situation arises where no service facilities are available, the following procedures may be used.

Turn off ignition and set transmission selector to Neutral (N) position.
Remove white plastic wheel saver from road side rear luggage compartment.

rails with jack stands or blocks before working under or around the coach.
Remove lug nuts and wheel assembly.

dimpled sides together before installing.

CAUTION!!
Severe injury or death may result. DO NOT use the leveling system for changing tires or
working under the vehicle. Keep the rear wheels in fi rm contact with the ground with the parking brake set.
With the leveling jacks extended, there is a possibility the vehicle may move either toward the front or the rear.

replace front or rear wheel until permanent replacement can be made. Road speed must not exceed 40 mph.
CAUTION!!
Bumpers are not designed for lifting and/or towing of the vehicle.
NOTE:
It is recommended that the wheel saver be used when loosening or torquing lug nuts.
