Tire Replacement
Failure to replace damaged tires with tires of the
same size, type, traction, and load rating than the
originally equipped tires can significantly affect the
weight carrying capacity, handling, and safety of your
motorhome.
WARNING WARNING
Ensure the spare tire is the same size and specifications
listed on your motorhomes Federal Weight Label.
WARNING WARNING
Tires degrade over time depending on many factors such
as weather, storage conditions, and conditions of use (load,
speed, inflation pressure, etc.) experienced throughout the
life of the tires. In general, tires should be replaced after six
years regardless of tread wear. Heat caused by hot climates or
frequent high-loading conditions, however, can accelerate the
aging process and may require you to replace the tires more
frequently.
You should also replace your spare tire when you replace the
road tires or after six years due to aging, even if has never been
used.
Replacement tires should be exchanged with the same size,
type, load rating, traction, and temperature rating of the
original equipped tires. Tire specifications are listed on the
motorhome's Federal Weight Label or found within the chas-
sis manufacturer's owner's manual.
NOTE: Installing replacement tires with a higher limit
than that of the originals DOES NOT increase the
payload capacity of the motorhome. Refer to the
chassis manufacturer’s owner’s manual for additional
information.
Always follow the vehicle manufacturer’s instructions
and procedures for jacking and securing the motorhome
when tire changing is necessary.
CAUTION CAUTION
Changing a Damaged Tire
If you experience a flat tire while driving your motorhome:
• Gradually decrease your vehicle speed; braking lightly if
possible.
• Hold the steering wheel firmly, direct the motorhome to
a safe place along the side of the road.
• Once safely parked, place warning markers as described in
Section 3, Emergency Stopping.
• If you need assistance, contact a road service provider, a
qualified RV or tire service repair center, or if an emer-
gency, call 911 (in the U.S.) for assistance.
• Make sure the road service technician reads and is famil-
iar with the tire changing information provided by the
chassis manufacturer. Make sure the wheel nuts have been
tightened to the proper torque as outlined in the chassis
manufacturer’s owner’s manual.
NOTE: There are factory-installed components at-
tached to the undercarriage of your motorhome. Be
sure jacks and jacking devices do not contact and
damage undercarriage components.
