General Safety Requirements
WARNING! Use only original equipment manu-
factured (OEM) components. Use of non-original
equipment could cause wheel breakage and
wheel separation from vehicle, which could
result in an injury accident. Each mounting sys-
tem is engineered only for use with its correct
mating part. Be sure that properly matched com-
ponents are used for each type of mounting. The
comparison chart on Page 177
illustrates the dif-
ferences between parts used in hub-piloted
mount and ball seat mount applications. Only
OEM 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 per-
son 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 seriously 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 sudden tire failure and
loss of vehicle control.
• Follow all warnings and cautions contained within
the tire and wheel manufacturers literature.
• Only properly trained personnel should service tire
and rim assemblies.
• See page 179
for specific safety requirements for
trucks with hydraulic brakes.
