Inspection:
– Inspect the tyre tread and side wall for damage, if necessary
remove any foreign bodies from the tyres, such as nails or
glass splinters.
– Inspect tyres for scrubbing, tread worn down on one side, po‐
rous side walls, cuts and punctures. Any defects found must
be advised to the customer and the customer's attention must
be drawn to any necessary repair measures!
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 er‐
rors.
– If such signs of wear are found, determine the cause by check‐
ing the chassis alignment (repair measure).

Minimum tyre tread depth
• The minimum tread depth is specified by applicable national

Tread wear indicators
The tread wear indicators (1.6 mm ridges) are located at multiple
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 manufacturers
instead of ridges.
If the tyre tread depth is close to the legal minimum, the customer
should be informed of the necessary tyre change.

– Position the inspection pin - T40139A- with the bead onto the
outer tread of the tyre -arrow-.
