Lateral runout check
Pretension the tire dial gauge about 2 mm.
Attach the indicator to the sidewall of the tire (pic. 4.15).
Spin the wheel slowly.
Record the minimum and maximum pointer deflection.
NOTE: If the difference is greater than 1.3 mm, then the lateral runout is considered to be exceeded. In this case, you can reduce it using minimization. Deviations of the indicator needle due to small irregularities on the rubber should not be taken into account.
Checking radial runout
Pretension the tire dial indicator about 2mm (pic. 4.16).
Attach the indicator to the tire tread.
Spin the wheel slowly. Record the minimum and maximum pointer deflection.
NOTE: If the difference is greater than 1 mm, then the radial runout is considered to be exceeded. In this case, you can reduce it using minimization.
Checking the radial and lateral runout of the wheel
Place the wheel on a balance stand.
Use the self-expanding collet adapter for VAS 5271 balancers.
Pretension the tire dial gauge about 2 mm.
Spin the wheel slowly. Record the minimum and maximum pointer deflection.
S - Lateral runout.
H - Radial runout.
Compare the obtained value with the nominal parameters in table 4.4.
NOTE: Deviations of the indicator needle due to small bumps on the rubber should not be taken into account.
NOTE: If the measured value is greater than the nominal value, normal running will not be achieved.
