VEHICLE LOADING PART 8: MAINTENANCE AND SERVICE
– 166 – Y53-6007 (R10/06)
WARNING! Improperly mounting and demount-
ing tire and rim assemblies is dangerous. Failure
to observe proper precautions could cause the
tire-rim assembly to burst explosively, causing
serious injury or death. See the wheel manufac
-
turer's literature for the proper way to mount and
demount your tires and rims. Follow their pre
-
cautions exactly.
WARNING! Use only components marketed by
PACCAR Parts. Use of non–original equipment
could cause wheel breakage and wheel separa
-
tion from vehicle. Each mounting system is
engineered only for use with its correct mating
part. Be sure that properly matched components
are used for each type of mounting. The compar
-
ison chart on page 142 illustrates the differ-
ences between parts used in hub-piloted mount
and ball seat mount applications. Only PACCAR
Parts supplied hub-piloted or ball-seat mounted
wheels may be used on this vehicle.
•If you are not fully qualified and not equipped
with the proper tools and equipment, do not
attempt to raise the vehicle or remove or
install the damaged tire and wheel assembly.
Obtain expert help. A person can be seriously
injured and/or damage can result from using
the wrong service methods. Truck tires and
wheels should be serviced only by trained
personnel using proper equipment. Do not
reinflate a tire that has been run flat or is seri
-
ously low on air without first removing the tire
from the rim and inspecting for damage
.
• Follow OSHA regulations per section
1910.177.
• Do not exceed the speed rating of tires.
Exceeding the speed rating may result in sud-
den tire failure and loss of vehicle control.
• Follow all warnings and cautions contained
within the tire and wheel manufacturers litera
-
ture.
• Only properly trained personnel should ser-
vice tire and rim assemblies.
• Do not exceed the load rating of your tires
(molded on the side wall of your tire) or the
maximum vehicle load rating, whichever is
less. Overloading could result in premature
tire failure causing you to loose control of
your vehicle and result in an injury accident.
The maximum vehicle load rating (GVWR) is
found on the Tire and Rim Data label on the
driver's door
.
