Underinflation
When an underinflated tire is run at normal
highway speeds, it flexes too much and builds up
heat. This heat damages the inner liner, casing
and outer sidewall of the tire. If not remedied
quickly, the tire will be irreparably damaged.
In extreme cases, the sidewall of the tire
is destroyed, both from the excessive heat
it endured due to the weight of the vehicle
pressing on the tire casing without the
cushioning load carrying effect of the correct air
pressure, and the crushing/cutting action of the
wheel as it rolls on the underinflated sidewall.
According to guidelines put out by the Rubber
Manufacturers Association (RMA), any tire that
has been run at less than 80% of recommended
air pressure for the load it is carrying should be
inspected for possible damage.
When one tire in a dual configuration comes
out of service due to underinflation damage,
the other tire in the dual configuration should
be inspected immediately. If the unserviceable
tire was underinflated, that means the
serviceable tire was carrying more and more of
the load for that wheel position. Consequently,
it too may have suffered some casing damage
due to overloading.
Air Pressure Check
You should check the air pressure every two
weeks or at least once each month and before
any trip. Your RV tires’ air pressure should be
checked every “drive” morning on long trips. On
short trips of a day or less driving each way, your
tires should be checked before you leave on your
trip and again before you start your trip home.
Check your tires when they are “cold” and have
not been driven for more than one mile. The
stated load capacity for a given cold inflation
pressure is based on ambient outside temperature.
If you must check your tires when they are
warm or hot, do allow for a slight increase in air
pressure and make sure they are within a couple
of pounds of each other on the same axle.
Frequently check tires. If a tire picks up a nail or
screw that creates a slow leak and causes some
air pressure loss, you might eventually spot it
visually if it is a front tire. If it is an outside
rear dual, you might also spot it with a visual
inspection. However, if it is an inside rear dual,
the chances of spotting it without an air pressure
check are very slim. If you begin driving without
finding it, very quickly (in most cases a few
miles) your outside rear tire next to the low air
pressure tire is going to heat up from carrying
double its load, which if left un-remedied will
eventually will cause both tires to fail.
Tire Replacement
Replacement tires must be the same size, type and
tread depth per axle, and have at least the same
weight carrying capacity as the original equipment.
Tires supplied by various manufacturers of the
same size and rating may not have the same weight
carrying capacity and maximum cold inflation
pressures. Consult your tire dealer. The original
equipment wheels and tires supplied on your motor
home have weight carrying capacities to support
Gross Axle Weight Ratings (GAWR) as stated
on the Federal Certification Tag attached in the
driver’s compartment .
If You Get a Flat Tire
In case of sudden tire failure:
• Apply the accelerator to maintain
directional stability, then gradually release
the accelerator.
• Use moderate brake pedal pressure.
Do not pump the brake. The vehicle is

NOTE
The motor home will tend to “pull” toward the side with
the flat tire.

NOTE
Per Department of Transportation regulation, all tires
are to be “stamped” with their weight rating, size,
maximum inflation pressure and manufacturing date.
