Checking The Tyres - Kettler Quadriga Comp Belt Translation Of Original Operating Instructions

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.

2 Check the side walls for wear. If there are any
cracks or tears, the tyre must be replaced.

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