13.3 Tyre specifications
13.4 Handling of tyres
 Drive over kerbs at an obtuse angle. Otherwise the flanks of the tyres may
get pinched. Driving over a kerb at a sharp angle can damage the tyre and
result in it getting ruptured.
 Drive over high manhole covers at a slow speed. Otherwise the tyres may
get pinched. Driving over a high manhole cover at high speed can damage
the tyre and result in it getting ruptured.
 Check the shock absorbers regularly. Driving with poor shock absorbers
significantly increases wear.
 If the tread wear is uneven, have the toe-in and the wheel camber checked.
Driving with an incorrectly set toe-in or a one-sided wheel camber leads to
a significant increase in wear.
 Avoid block brakings. Block braking gives the tyres "brake plates" of var-
ying strength. This reduces driving comfort. It might even make the tyres
unserviceable.
 Do not clean the tyres with a high-pressure cleaner. The tyres can suffer
serious damage within just a few seconds and rupture as a result.
 Drive in such a way as to protect your tyres. Avoid braking sharply, revving
up too strongly and long journeys on poor roads.
