Excessive loads and/or under inflation cause tire overloading and, as
a result, abnormal tire flexing occurs. This situation can generate an
excessive amount of heat within the tire. Excessive heat may lead to
tire failure.
It is the air pressure that enables a tire to support the load, so proper
inflation is critical. Since RVs can be configured and loaded in many
ways, air pressures must be determined from actual loads
(determined by weighing) and taken from the load and inflation tables
provided by the tire manufacturer. These air pressures may differ
from those found on the certification label. However, they should
never exceed the tire limitation for load or air pressure. If you
discover that your tires cannot support the actual weights, the load
will need to be reduced.
Tire Safety Tips —— Preventing Tire Damage
• Slow down if you have to go over a pothole or other object in the
road.
• Do not run over curbs or other foreign objects in the roadway,
and try not to strike the curb when parking.
Note: Tires are warranted by the manufacturer of their
respective brand and are to be serviced and warranted by a service
center. Contact your dealer for information on service centers for
tires.
