Steel Wheel Mounting Surface Check

1. Place straight edge (about eight to nine inches long) with both hands on inboard mounting surface of wheel.
2. Try to rock straight edge up and down.
^ The outer ring of mounting surface is normally raised above everything else inside it. If surface has been bent on a tire changer, it will be raised above-outer ring and straight edge will rock on this position.
3. Repeat steps 1 and 2 at three or four different positions on inboard mounting surface.
4. If wheel is bent, it must be replaced. Refer to "Wheel Removal and Installation".
