Tire Pressure
You must follow the manufacturer’s inflation guidelines for maximum load capacity;
under-inflation is just as dangerous as over-inflation.
Proper inflation should be monitored closely. Failure to do so could result in the overheating
of a tire causing a blowout. Inflation pressure should be as recommended by the tire manu
-
facturer or as the federal label for the recreation vehicle indicates.
When you are using your Recreational Vehicle, check inflation pressure weekly. Pressure
should be checked when the tires are cold. During travel, tires heat up and pressure increas-
es.
Do not bleed air from hot tires or your tires may then be under-inflated.
Tire wear should be checked frequently. Once a wear pattern becomes firmly
established in a tire it is difficult to stop, even if the underlying cause is cor
-
rected.

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.

It is recommended that the tire pressure be checked at the beginning of
each trip to obtain the maximum life of the tire. Follow the instructions
listed on the Federal Certification label, to determine the correct tire pres

sure. Under-inflation may cause tire failures and swaying resulting in loss
of control, injury, death or property damage.
