Storage Of Tires; Long Term - Monaco 2002 Diplomat Service Manual

aging, use extra care and caution. Tire dressings that contain petroleum
products or alcohol may cause deterioration or cracking.
In many cases it is not the dressing that causes a problem but the chemical
reaction that subsequently occurs. When these same dressing products are
used on a passenger car tire that is replaced every three to four years, it is
rare to see a major problem. However, in most cases, RV tires may last
longer due to limited annual mileage and exposure.
The motorhome is designed for recreation, not long-term storage.
However, unless the vehicle is being used full time storage will be required.
Rubber tires age faster when not being used. A cool, dry, sealed garage is the
best bet for storage. Many motorhomes are stored outside in the elements.
Some storage surfaces may cause tires to age prematurely. When the tire is
anticipated to be out of service for a period of three months, the motorhome
should be in the long-term storage condition. Ideal conditions include plac-
ing the motorhome on blocks to remove all weight from the tires. With this
method the inflation pressure can be reduced to 15 PSI. However, this is not
always possible, with a few simple steps the aging effects from long-term
storage or a non-use period can be reduced.
• Thoroughly clean the tires.
• Unload the motorhome so there is minimum weight on the tires.
• Ensure the surface is reasonably level, firm, clean and has good
drainage.
• The tire inflation pressures should be increased to 25% above the actual
load when the tire is placed in the storage condition.
• Move the motorhome every three months to prevent cracking in bulb
areas as well as flat-spotting from prolonged sidewall strain and tread
deflection.
• Cover the tires to block direct sunlight and ultraviolet rays.
• Store the motorhome out of high ozone areas.
Failure to take these steps can cause early deterioration and shorten the
life of the tires.
NOTE: When the motorhome is stored the tires should be
inflated to maximum inflation pressure as indicated on the
sidewall of the tire.
Before removing the motorhome from long-term storage thoroughly
inspect each of the tires. This means a close examination of each tire's tread
area and air pressure. If the pressure check indicates the tires have lost air
during storage, inflate them to the correct pressure for the current load before
putting the motorhome into service.
