Procedures for inspecting and installing on vehicles

Warning: improper parts and incorrect installation procedures could cause a wheel to fail in service. A serious, even fatal could be resulted. Follow all instructions for inspecting and installing rims/wheels. Do not substitute parts. Remember:

Wheels must be mounted with required studs. Stud types are not interchangeable.

Nuts must be retorqued routinely. Use the proper nut torque and tightening sequence.

Each tire, wheel, and axle has its own maximum rating. Do not load and inflate the tire/wheel/axle system beyond the rating of the lowest rated component.

Inspections and preparation instructions

1. During tire inspections or periodic vehicle instructions

(1) Check all metal surfaces thoroughly, including both sides of the wheels (if duals, including areas between duals), watch for excessive rust or corrosion buildup; cracks in metal; bent, broken flanges or components; loose, missing, or damaged nuts; bent or stripped studs; and incorrectly matched rim parts.

(2) Replace an assembly that is damaged or has damaged components.

Warning: excessively corroded or cracked rims are dangerous, especially during the removal of the assembly. Make sure that deflating tire(both tires if duals) or may cause serious damage.

(3) Look for rust streaks which indicate loose nuts or improper nut fit. After tightening the nuts to the recommended torque level or replacing them, remove the rust streaks.

(4) Replace broken studs and each unbroken stud next to the broken stud.

(5) Determine the cause of the damage before installing another wheel.

(6) Inflate tires to only the recommended air pressure.

2. Installation procedure

(1) Inflate tire before installing on vehicle

(2) Iinspect parts before installing

(3) Install wheel on vehicle

(4) Torque nuts properly
