6.15.2 Tread
Tread analysis can be performed
1. During the balancing cycle to obtain an average value measured over the whole tyre width.
No extra time is required.
2. Enable a special measuring cycle using the button to obtain the tread value for the three different areas:
inside edge, centre and outside edge of the tyre.
The cycle time is slightly longer.
The tread values that are out of tolerance are shown in red.
Use of the wheel balancing machine
displayed when at least one tread value is out of tolerance.
displayed when all the tread values are within tolerance
By law (to be verified for each country) the minimum tread thickness must be 1.6mm at each point.
It is quite normal for tyres to wear irregularly and that the pivot pins wear more on one side.
By means of tread analysis at several points, you can measure the tyre tread depth with adequate accuracy on the
edges and in the centre.
