TIRES AND WHEEL
Underinated Tires
Low pressure
is a tire’s worst enemy.
Underination allows tires to ex
improperly, causing high temperatures
to build up. Heat causes early tire
damage such as ex break, radial
cracks, and ply separation. Low
pressure may affect control of your
vehicle, especially at the front wheels.
Most tire wear problems are caused
by underination as the result of slow
leaks, so you’ll want to check tire
pressure regularly. Lower tire pressure
does not provide better traction on ice
or snow.
WARNING!
WARNING!
Do not operate a vehicle with underin-
ated tires. The extra heat caused by
underination can cause sudden tire
failure such as a tire re or blow out,
which can cause an accident result
-
ing in death or personal injury. Low
pressure may affect control at the front
wheels, which could result in an acci
-
dent involving death or personal injury.
Keep your tires inated to the manu
-
facturer's recommended air pressure.
Do not attempt to raise the vehicle to
remove or install a damaged tire and
wheel assembly if you are not fully
qualied and not equipped with the
proper tools and equipment. Do not at
-
tempt to re-inate a tire that has been
run at. Obtain expert help. A person
can be seriously injured or killed if us
-
ing the wrong service methods. Truck
tires and wheels should be serviced
only by trained personnel using proper
equipment. Follow OSHA regulations
per section 1910.177.
