7.5.1.2 Checking the tyres
The tread is far less important for bicycle tyres
than it is for car tyres, for example. Consequently,
tyres can still be used with a worn tread with the
exception of tyres on mountain bikes.
1 Check the tread wear. The tyre is worn if the
anti-puncture protection or the carcass cords
are visible.
Since resistance to punctures also depends on
the thickness of the tread, it may make sense
to change the tyre at an earlier stage.
Figure 144: Tyre without tread which can still be used (1)
and tyre with puncture protection showing through (2),
which needs to be replaced
2 Check the side walls for wear. If there are any
cracks or tears, the tyre must be replaced.

cracks (2)
 Replacing a wheel requires considerable
mechanical expertise. If a tyre is worn, it needs
to be replaced at a specialist dealer's.
