Replacing Your Tires
Proper Inspection and Storage of Tires
Before taking your RV on a trip or when removing from an extended storage
period, make it a practice to inspect the overall condition of your tires. Check
for any type of condition or damage that might result in failure. A thorough
check should include both inside and outside sidewalls, tread area and the
condition of hardware such as valve stems, valve caps, and wheels. The tread
should be checked for any unusual wear, cracking, penetrations and/or cuts.
An uneven wear pattern can indicate misalignment or worn suspension parts.
Since many RVs are used seasonally and sometimes stored for extended
times, it is possible that tires will take many years to wear out. Tires, as any
rubber product, will age over time. If tires show cracking in the sidewall or tread
surfaces that are more than 2/32nds deep, they should be replaced before
your next trip or vacation. Store your RV in a cool dry area away from major
heat sources and extreme cold. An enclosed area is best with no exposure to
electromagnetic sources such as generators or transformers. If you must keep
your RV outside, cover your tires from direct sunlight. Take your RV to your Tire
dealer for service to check or correct any of these conditions.
It is possible to replace your tires with a different size in some instances to
increase your load capacity with a different inflation pressure. If there is a reason
to replace your tires with a different size, make sure the following checks are
made before the purchase.
• Does the replacement tire have the load capacity that is needed for my
RV and will it fit properly inside the wheel well?
• Will the overall diameter difference affect the speedometer or antilock
braking system?
• Is the increase in air pressure compatible with the maximum rated
pressure stamped on the rim?
• Is there enough dual spacing offset for the rear wheel positions?
Tires used on most RVs are driven at or near maximum loads during hot
weather and then are left idle for months. In normal use oils in the tire come to
the surface during flexing and protect the rubber from ultraviolet light. But when
left idle natural aging may cause the rubber to crack prematurely, especially in
the sidewall area.
Any tire on an RV that is over five years old should be inspected by a competent
tire professional for cracking and replaced, even if it has no apparent tread
wear. This is because a tire on a car or truck might last 80,000 to 120,000 miles
