- Surface of the wheel must be clean and dry.
- All tire and wheel assemblies are to be checked for static tolerance of 2 grams and not more than 20 grams per plane, using cut-to-length weight produced by 3M cutting machine.
- Car - Flanged - inboard & outboard – 71 grams per plane.
- Truck - Flanged - inboard & outboard – 142 grams per plane.
- Car - Flangeless - inboard & outboard – 142 grams per plane.
