When you are using your motorhome, check the inflation pressure of each tire weekly to
insure maximum tire life and travel wear. Tire pressure should only be checked when the tires
are cold. During travel, your tires heat up and the air pressure inside the tire increases.

Lug Nut Torque

Being sure wheel mounting nuts (lug nuts) on the wheels are tight and properly torqued
is an important responsibility that you need to be familiar with, and practice. Inadequate
and/or inappropriate wheel nut torque (tightness) is a major reason that lug nuts loosen in
service. Loose lug nuts can rapidly lead to a wheel separation with potentially serious safety
consequences.
Refer to the chassis manufacturer's information for proper lug-nut torque and tightening
sequence.
