Tires, wheels, and towing
TIRES
The tires (original) supplied are designed to meet the federal specifications and to provide a reliable and safe mode
of transportation. Since the tires are the sole component between the road and your vehicle you must provide
the proper care and maintenance to help ensure your safety and helps to maximize the life of the tires. When a tire is
replaced be sure to stay within the guidelines listed on the Federal ID tag
.
TIRE PRESSURE
Keeping your RV tire pressure at the proper levels will help ensure your safety and the life of your tire. Under
inflated or over inflated tires can result in damaging the tire and causing a handling problem with the vehicle.
Inflation pressure should be adjusted to handle the maximum tire load, and all tires on the axle should carry the
same inflation pressure.
Never reduce the tire pressure below the vehicle manufacturer’s recommended levels to support load conditions
to try to improve the ride quality of a vehicle. The difference will not significantly change and or the value of tire
durability and optimum operation will be affected. Inflate the tire pressures to specification listed on the
Certification Label, located in the driver’s door.
Check when tires are cold, this is either when the motor home has not been driven more than one mile or that has
sat at least 3 or more hours. Failure to keep the tires properly inflated can cause damage or premature wear of
tires and waste gasoline.
Under inflated tires can cause the tire to overheat, which can result in the tire losing
air suddenly and could catch on fire.
Over inflated tires are more likely to be cut or punctured by sudden impact (such
as a pothole) and result in a serious accident. Check all tires frequently to
maintain the recommended pressure.
Either of these conditions can result in bad handling resulting in a serious accident.
TIRE MAINTENANCE
Motorhome tires need extra care and attention and must be properly maintained to help ensure safe transportation and
maximize the life of the tire.
TIRE INSPECTION
A visual inspection of the tires should be performed monthly, more often when camping, before leaving on a trip,
and after an extended storage period.
Check each tire for proper inflation.
Check the valve stems and caps for damage.
Check for any type of road or curb damage to tread or sidewall areas.
Check both the inside and outside of the sidewalls and tread for tire of wear, cracking penetrations and/or cuts in
the tread or sidewalls.
Check for signs of overloaded or under inflated tire use. This can show up as unusual discoloration or waviness in
the side walls, bulging in the bead area near the rim flange or a progressive tread wear on one tire more than the
others
