TIRES
Tires designed for the motorhome are a very technical and engineered product. Since the tire is the only
contact the motorhome has with road surface, it is critical that proper tire pressures be maintained. Improper tire
pressure will lead to abnormal wear or sudden tire failure. The motorhome must be weighed fully loaded before
proper tire infl ation pressures can be determined. The following information concerning tires and weighing the
motorhome are set in the order in which the process is performed or experienced.
The tire performs additional functions of traction for moving stopping and steering, as well as providing a
cushion for the motorhome. Modern tire technology blends a unique mix of chemistry, physics and engineering to
provide a high degree of comfort, performance, effi ciency, reliability and safety. To obtain the maximum wear and
best service from tires, it is helpful to understand the components and functions of the tire.
Tire Components:
Tread:
Provides traction and cornering grip.
Belts:
Stabilize and strengthen the tread.
Sidewall:
Protects the side of the tire from road
and curb damage.
Body Ply:
Gives the tire strength and fl exibility.
Bead:
Assures an air-tight fi t with the wheel.
Inner Liner
: Keeps air inside the tire.
Importance of Air Pressure
The most important factor in maximizing the life of the tires is maintaining proper infl ation. Driving on any
tire that does not have the correct infl ation pressure for the load of the motorhome is dangerous and may cause
premature wear, tire damage and/or loss of control of the motorhome.
An under-infl ated tire will build up excessive heat that may go beyond the design limits of the rubber and
radial cords and could result in sudden failure. An under-infl ated tire will also cause poor motorhome handling,
rapid and/or irregular tire wear and an increase in rolling resistance that results in a decreased fuel economy.
An over-infl ated tire will reduce the tire’s footprint/contact patch with the road, thus reducing traction, braking
capacity and handling of the motorhome. Over-infl ation of a tire for the load will result in a harsh ride, uneven tire
wear and a susceptiblity to impact damage.
Maintaining correct tire infl ation pressure for each loaded wheel position on the motorhome is of the utmost
importance and must be a part of regular motorhome maintenance.
WARNING:
Driving on a tire that is under-inflated can exceed the design limits of the tire and may
damage the sidewall. A damaged sidewall can burst upon inflation resulting in serious
damage, injury or death. Aged tires are also susceptible to sidewall damage.
