Inspecting tyre wear
– The wear pattern on the front tyres makes it possible to
assess whether it is necessary to inspect the wheel toe and
camber:
♦ The formation of ridges on the tyre tread is an indication of
wheel toe errors.
♦ Tread worn on one side is usually attributable to camber
errors.
– If such signs of wear are found, determine the cause by
checking the chassis alignment (repair measure).

Minimum tyre tread depth
• The minimum tread depth is specified by applicable national
legislation (may be different in different countries).
Tread wear indicators
The tread wear indicators (1.6 mm ridges) are located at multi‐
ple points around the tyre circumference -arrows-. The position
of the tread wear indicator is shown on the tyre side wall by the
TWI lettering, an arrow (triangle) or the manufacturer's logo.
A "numerical tread wear indicator" is used by some manufactur‐
ers instead of ridges.
If the tyre tread depth is close to the legal minimum, the cus‐
tomer should be informed of the necessary tyre change.
Check tread depth
The tyre tread depth is check with the inspection pin -T40139A-.
– Position the inspection pin -T40139A- with the bead onto the
outer tread of the tyre -arrow-.
