Wheels and Tires: Testing and Inspection




Wheel Mounting Surface Check

1. Clean any grease and any road dirt from the wheel.
2. Clean the rubber from the bead seat using a wire brush or steel wool.

Notice: Do not heat wheels in an attempt to soften them for straightening or repair damage from striking curbs, etc. Do not weld wheels. The alloy used in these wheels is heat-treated and uncontrolled heating from welding affects the properties of the material.

3. Inspect the gutter areas for bulges. Remove any bulges that you find.
Bulges will cause the following conditions:

* Uneven seating of the side ring
* Uneven seating of the lock ring
* Chipping of the gutter

4. Inspect the mounting area for bulges. Smooth any bulges that you find.
5. Inspect the fixed flange area for nicks and gouges that may cause rim fracture.
