Checking lateral run-out

–	Preload tyre gauge approx. 2 mm.

–	Fit tyre gauge to side wall of tyre.

–	Turn wheel slowly.

–	Make a note of the smallest and largest deflection of the indicator needle.

Note

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

In this case, you can reduce lateral run-out by match mounting the tyre → Chapter.

Extreme values on the tyre gauge due to small irregularities in the rubber may be disregarded.

Checking radial run-out

–	Preload tyre gauge approx. 2 mm.

Checking radial and lateral runout on wheels and tyres with tyre gauge
