Match Mounting Tires

Match mounting is a technique used to reduce radial runout. Excessive runout is a source of vibration, shimmy and poor handling concerns. Use the following steps to reduce radial runout:

1. Mark the wheel at the same point as the mark previously made when measuring the tire runout.
2. Dismount the tire and remount it 180 degrees on the wheel so the original mark on the tire is opposite the mark on the wheel.
3. Inflate the tire to specification.
4. Measure the radial runout with Radial Runout Gauge at the center of the tread face: If the radial runout is reduced to acceptable guidelines, the tire can be used: If the radial runout remains excessive, check the wheel runout.
