Radial And Lateral Run-Out On Wheels/Tires, Checking With Tire Dial Gauge : VAG1435
Checking Lateral Run-Out:
-- Preload tire dial gauge approximately 2 mm.
-- Position dial gauge on tire side wall as shown in illustration.
-- Slowly rotate the wheel.
-- Note the smallest and the largest dial readings.
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 MATCHING .
Peak values on the tire dial gauge due to small irregularities in the rubber may be disregarded.
Checking Radial Run-Out:
-- Preload tire dial gauge approximately 2 mm.
-- Position dial gauge on tire running surface as shown in illustration.
-- Slowly rotate the wheel.
-- Note the smallest and the largest dial readings.
If the difference is greater than 1 mm, the radial run-out is too great.
In this case, radial run-out can be reduced by matched mounting of the tire. Refer to MATCHING .
