6. Offset. This refers to the relationship of the center line of the tire to the hub face
of the axle. Care should be taken to match a replacement wheel with the same offset
wheel as originally equipped. Failure to match offset can result in reduced carrying
capacity of your axle.
7. Rim Contour.
RIM CONTOURS!
Use only the approved rim contours as shown in the Tire and Rim
Yearbook or the tire manufacturers catalog. The use of other rim con-
tours is dangerous. Failure to use the proper rim contour can result in
explosive separation of the tire and wheel and could cause a serious
accident.
WHEEL MODIFICATIONS!
Do not attempt to repair or modify a wheel. Even minor modifications
can have a great effect. Do not install a tube to correct a leak through the
rim. If the rim is cracked, the air pressure in the tube may cause the
pieces of the rim to explode with great force and can cause serious injury
or death.
Wheel Torquing Procedures
When installing the wheels, make sure that the hub and wheel mating surfaces are
clean and free of rust, dirt and excess paint. The studs and threads must be clean, dry
and in good condition for applying installation torque.
The hand torque wrench or air wrench used to install the wheels must be periodi-
cally calibrated to insure proper applied torque. Adjust the tools as necessary.
Position the inner disc wheel over the studs, being careful not to damage the stud
threads. Make sure the disc wheel is flat against the mounting surface and there is
clearance between the disc wheel taper and the brake drum.
Position the outer disc wheel over the inner disc wheel being careful not to damage
the threads on the studs. Be sure the valve stems for both the inner and outer tires are
accessible.
Install the flange nuts and tighten to a partial torque of 50 lbs.-ft. using the se-
quence shown, and then tighten the flange nuts to a full torque of 450-500 lbs.-ft. in
sequence.
