Tire Rotation
Tire rotation can increase the useful life of the tires by achieving uniform wear on all of the tires. Have the
tire manufacturer determine the rotation pattern. The fi rst tire rotation is the most important in determining
which rotation pattern to use. Any unusual or unique wear patterns, or indications of uneven wear that may have
developed, should be evaluated for possible tire rotation. Misalignment, imbalance or other mechanical problems
may exist and will need to be corrected prior to rotation.
Tread
To prevent skidding and hydroplaning, replace tires when the tread is worn down to 4/32" on the front, and
2/32" on the rear. Questions regarding tread wear should be directed to the tire manufacturer.
Built in tread wear indicators, or “wear bars” which look like narrow strips of smooth rubber across the tread,
will appear on the tire when the tread is worn down to 1/16". The tire should be replaced when wear bars are noticed.
Visually check the tires for signs of uneven wear. Signs of irregular tread wear are usually exhibited by low or
unusually smooth areas on the tire surface. Consult the tire manufacturer as soon as possible.
WARNING:
In many instances the life of the tires on the motorhome is not determined by mileage but
by age. Tires are subject to weathering. Weathering cracks run in circumference with the
tire. Though the sidewall of the tire may look fine and be structurally sound, weathering can
occur inside the well of the tread, therefore replacement may be determined not by mileage
but age. Have the tire manufacturer inspect the tires for age weathering.
Storage of Tires - Long Term
A cool, dry, garage with a sealed cement fl oor is the preferred method of storage. Tires stored outside may
prematurely age.
Prior to Storage:
• Thoroughly clean the tires.
• Unload the motorhome to reduce weight on the tires.
• Ensure the surface is reasonably level, fi rm, clean and has good drainage.
• Infl ate the tires to the maximum infl ation pressure as indicated on the Federal Identifi cation Tag.
During Storage:
• Cover the tires to block direct sunlight.
• Periodically ensure tires are at proper pressure.
• Move the motorhome every three months to prevent cracking in bulge areas, as well as fl at spotting from
prolonged sidewall strain and tread defl ection.
Removal from Storage:
• Before removing the motorhome from long-term storage thoroughly inspect each tire’s tread area and air
pressure. If the tires have lost air during storage, infl ate them to the correct pressure.
