MEASURING WHEEL RUNOUT

FIGURE 1 - Radial Runout
Radial/Lateral Runout
This bulletin supersedes Serviceman Bulletin T-84-12, Group 3E, Number 14, which should be destroyed.
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.
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. 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 limits, 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.
