Wheel beating
Measure the wheel runout with an accurate dial indicator. The measurement can be taken either with the wheel on the vehicle or with the wheel off and on a suitable flat surface, such as a wheel balancer. The measurement can be taken with or without the tire.
Measure the radial and lateral runout at both the inner and outer rim flanges. With a dial indicator securely mounted next to the wheel and tire assembly, slowly rotate the wheel one revolution and record the indicator reading. If any measurement is greater than the specifications and there is any doubt as to whether the wheel is properly balanced, the wheel should be replaced. Ignore any indicator readings that are due to welds, paint runs, or scratches.
Measure the radial runout of a free-wheeling wheel in the middle of the tread. To make the tread surface smooth, you can stick some tape on it. Measure the lateral runout of a free-wheeling wheel on the outside sidewall of the tire, as close to the tread as possible.
Steel/alloy wheels
- Radial runout: 0.8 mm (0.03 inches)
- Lateral runout: 1.0 mm (0.04 inches)
