Measure the diameter of the wheel at multiple
points over the width of the wheel.
The diameter may
not be smaller than is specified in the table.
If the diameter is smaller, the wheel must be replaced.

This means that the permissible deviation in the diameter of opposite-lying driven wheels is limited.
Determine the difference in diameter of the
opposite-lying driven wheels.
The difference in diameter may not be larger than is specified in the table.
If the respective diameters of the wheels deviate from each other by more than this, the wheels must be replaced.
