Wheels and tyres

Weight refers to the maximum permissible axle load which can be distributed
on two tyres. The maximum load-carrying capacity of a tyre is indicated by its
load index (= LI, load index code).
The axle geometry of a vehicle, such as wheel camber and track, is also
important for tyre selection. The maximum permissible speed for a tyre (with
full load-carrying capacity) is indicated by the speed index (= SI). Together,
load index and speed index form the operating code of a tyre. This is an official
component of the complete, standardised dimensions description which
appears on every tyre. The information on the tyres must correspond to the
specifications which appear in the vehicle papers.
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.
„
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.
