Read and understand the following before taking your first trip in your recreation vehicle!
Proper care and maintenance of your tires is essential to ensure your safety, as well as the
safety of others, as you travel.
Routine maintenance on your recreation vehicle is important, but it cannot be overstated just
how critical proper tire maintenance is to the safety, operation and durability of your new
vehicle.
You must follow the manufacturer’s inflation guidelines for maximum load capacity; under-
inflation is just as dangerous as over-inflation.
To insure your tires are operating safely, regular inspection of your tires and checking tire
pressures is absolutely mandatory.
Examine your tires frequently for unusual wear. Alignment, balance and bearing wear will
affect tire wear. Make sure to look for cracking, bulging, uneven tread wear, etc.
When you are using your vehicle, check inflation pressure weekly to insure maximum tire
life and travel wear. Pressure should be checked when the tires are cold. During travel, tires
heat up and pressure increases.
Do not bleed air from hot tires or your tires may then be
under-inflated.
Tire pressure is the most important factor in the life and performance of your tires. Proper
inflation should be monitored closely. Failure to do so could result in the overheating of a
tire, which could result in a blowout. Inflation pressure should be as recommended by the
tire manufacturer or as the federal label for the recreation vehicle indicates.
Check and tighten wheel lug nuts regularly to make sure they did not loosen
during travel. Wheel lug nuts must be applied and maintained at the proper
torque levels to prevent loose wheels, broken studs and possible separation of
the wheel(s) from your recreation vehicle. The lug nuts on the wheels of your
recreation vehicle must be maintained according to listed torque values (see
Wheel Lug Torque Chart.
) Over-torqued and/or under-torqued wheels may
result in component failure.
Failure to maintain proper torque of the wheel lug nuts could lead to
separation of the tire and wheel while driving, possibly resulting in
property damage or personal injury.

NOTE: Cold tire inflation pressure is defined as a tire that has not
been used for three or more hours, or has been driven less than one
mile. Tire inflation pressure of a hot tire may show an increase of as
much as 6 psi over a cold tire.
