MEASURING WHEEL RUNOUT - ALL MODELS
Wheel runout should be measured with an accurate dial indicator graduated in thousandths of an inch.. Measurements may be taken with the wheel
installed on the car, or off the car using an accurate mounting surface such as on a wheel balancer. Measurements may also be taken with or without the
tire mounted on the wheel.
MEASURING WHEEL RUNOUT
Radial runout and lateral runout should be measured on both the inboard and outboard rim flanges. Maximum runouts and recommended measurement
locations are shown in chart (shown on the reverse side). With the dial indicator firmly in position, slowly rotate the wheel one revolution and record the
TIR (Total Indicator Reading). If any measurement exceeds these amounts and if the vehicle should experience a vibration condition that wheel
balancing will not correct, the wheel should be replaced. Disregard any indicator jumps due to welds, paint runs, scratches, etc..
