Section 5: Tires and Wheels
Always be
attentive to
the condition
of your
motorhome’s
tires.
Tire Safety
Read and follow the safety instructions listed below before
traveling in your motorhome:
• Proper care and maintenance of the motorhome's tires is
essential to the safe operation of this motorhome.
• Following the tire ination guidelines, located on the
Federal Weight Label, is mandatory to achieve maximum
load capacity (see Section 6).
• Under-inflation of tires is just as dangerous as
over-ination.
• To ensure the motorhome tires are operating at their
peak performance and safety, regular tire inspection
and checking of tire pressures is mandatory.
• Wheel alignment, wheel balance, tire ination, improper
loading, and worn bearings will aect tire wear. Examine
the motorhome's tires frequently and inspect for crack-
ing, bulging, uneven tread wear, and other tire-related
issues.
When traveling in your motorhome, check the ination pressure
of each tire at least weekly to insure maximum tire performance,
and travel wear. Tire pressure should only be checked when the
tires are cold. When the motorhome is underway, tires heat up
and the air pressure inside the tire increases.

Tire Inflation and Inspection
Tires and wheels support the entire weight of this motor-
home and its contents. e tires are also the only contact
the motorhome has with the road surface. Determining
and maintaining proper tire inflation and weight (load)
restrictions are the most important factors in maximizing
the life of motorhome tires.
Driving on a tire that does not have the correct ination
pressure for the vehicle load is dangerous and may cause
premature wear, tire damage, tread separation and/or loss
of control of the motorhome. Avoid premature tire damage
by keeping tires properly inated.
Tire pressure under and/or over inflation can cause severe tire failure
Find your PSI:
PSI (pounds force per square inch) is a measure of air pressure
used to correctly inate the tires. e correct PSI listing
for both front and rear tires is located on the motorhome’s
Federal Weight Label (see Section 6). KPa (kilopascals) is
another commonly used air pressure measurement:
1 PSI=6.894 kPa
Checking Tire Pressures
Check all tire pressures (including the spare tire) before
and aer a trip and at least weekly while traveling, using an
accurate pressure gauge. Always check ination pressures
when the tires are cold. Correct tire inflation cannot be
determined by visual inspection only.
Failure to follow proper ination guidelines may result
in tire failure, which under certain circumstances, can
cause loss of vehicle control or accidents that may result
in property damage, bodily injury, and/or death.
DANGER
Check tire pressure at the beginning of each trip and
frequently throughout the trip to obtain the maximum
performance and life from the tires. Follow the
instructions listed on the Federal Certication label,
located inside your motorhome, to determine the correct
tire pressures.
