Wheel and Tire Radial and Lateral Run Out, Checking with Tire Dial Gauge

Special tools, testers and auxiliary items required

• Tire dial gauge (V.A.G 1435)

Checking Lateral Run-Out

- Load the (V.A.G 1435) approximately 2 mm.

- Set up (V.A.G 1435) on the side wall of the tire.






- Rotate the wheel slowly.

- 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 => [ Matched Mounting ] Matched Mounting.

Peak values on the (V.A.G 1435) due to small irregularities in the rubber may be disregarded.

Checking Radial Run-Out

- Load the (V.A.G 1435) approximately 2 mm.

- Set up (V.A.G 1435) on the tread of the tire.






- Rotate the wheel slowly.

- 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 => [ Matched Mounting ] Matched Mounting.
