Inspecting & Pressure - Monaco Cayman 2005 Owner's Manual

Check tire pressure regularly. A sharp object can lodge in a tire and create a slow leak. The object
will eventually be detected on a front tire, but may go unnoticed on one of the rear duals to result in
one tire carrying the weight intended for two. Exceeding weight limits the tire is designed to carry can
cause it to fail (in most cases only a few miles) resulting in two flat tires on the same axle and the same
side. The flat tire can also generate enough heat by friction for the tire to ignite.
Check the tire pressure every two weeks or at least once a month, and always before a major trip.
Check the tire pressure every "drive" morning on both long and short trips (driving a day or less).
Check the tire pressure before leaving on a trip and again before starting the trip home. Check the tire
pressure before storing the motorhome for any length of time. More importantly, check the tire pressure
when removing the motorhome from storage.
Check the tire pressure when the tires are "cold" and have not been driven for more than one mile.
The rated load capacity for cold inflation pressure is based on ambient temperature. If you must check
the tires when they are warm or hot, allow for a slight increase in air pressure. The pressure should be
within a couple of pounds of each other on the same axle. Never let air out of a hot tire.
When checking the inflation pressure, use a high-quality truck tire air gauge with an angle dual
head. This type of pressure gauge can check the pressure of the inner dual wheel that has the valve
stem pointing outward and the outer wheel that has the valve stem pointing inward. Nothing should
restrict the ability to easily check tire air pressure daily when traveling in the motorhome. Use valve
stem caps with a positive seal to prevent air escaping from the valve stem. If there are extension hoses
on the valve stem, make sure they are good quality reinforced stainless steel braid. Attach hoses
securely to the outer wheel.
Optimum tire performance is achieved at proper inflation pressure for the load carried. Do not mix
tires of different tread patterns on the same axle. The difference in traction could cause rear end
gear fight and mechanical damage to the drive train. Never mix tires of a different size or construction
on the same axle.
Higher than recommended pressure can cause:
• Hard ride.
• Tire bruising or carcass damage.
• Rapid tread wear in the center of the tire.
WARNING:
Improperly inflated tires can effect handling or cause sudden
tire failure possibly resulting in loss of vehicle control of the
motorhome. Always use an accurate tire pressure gauge when
checking tire pressure.
