CHASSIS OPERATIONS & PROCEDURES
WHEELS & TIRES
The motorhome tires play an important role in the load carrying capacity of the vehicle.
To ensure good tire life, check tires often. Inspect the general condition of the tires, as well as
the air pressure.
Always check the air pressure when the tires are cold. Tires that are hot from traveling will show
higher pressures. The maximum tire pressure and the load carrying capacity of the tire are
imprinted on each tire sidewall as well as on the vehicle serial number I.D. tag. Always inflate
the tires to their correct pressure. Do not over or under inflate. Under inflated tires will run hot,
shorten the tire’s life and decrease the motorhomes safe load limit. Over inflated tires will cause
a rough and bouncing ride that could damage motorhome components or cargo. It is a good
idea to always carry an accurate tire pressure gauge in the motorhome to make these checks.
If pressure checks indicate that a tire is losing air, check for signs of valve leakage, penetration,
or wheel and rim damage.
The way you drive can have a significant effect on the wear and life of tires also. High speeds,
unusual use of the brakes, taking corners too quickly, quick starts, and surfaces in poor
condition all can attribute to the early wear and failure of your tires.
DAMAGED OR FLAT TIRES
When replacing a tire, make sure that service personnel replace it with a tire of the same
size and specifications.
If you notice damage to a tire such as a bulge, uneven wear, or damage by a foreign object or
the road, have it inspected and repaired or replaced as needed. Remember that tires should be
taken to an authorized tire repair facility.
NOTE: If you experience a flat tire, it is recommended that you have qualified personnel with
the proper equipment handle the problem. Due to the size and weight of a motorhome wheel
and tire assembly, as well as the amount of torque needed to tighten wheel nuts securely, it is
best to call in a professional. It is for this reason that a jack has not been included in this
motorhome.
