-- Rotate the wheel slowly.

-- Note the smallest and the largest dial readings.

NOTE:

If the difference is greater than 1.3 mm, the lateral run-out is too great.

In this case, lateral run-out can be reduced by matched mounting of the tire. Refer to WHEELS AND TIRES, MATCHING .

Peak values on the Tire Dial Gauge due to small irregularities in the rubber may be disregarded.

Checking Radial Run-Out
