Wheels and tyres

Check regularly that the wheel nuts or wheel bolts are firmly seated. Re-
tighten the wheel nuts or wheel bolts of a changed wheel cross-wise
(Fig. 274) after 50 km (30 miles).
See section 13.5.2 for tightening torque.
When using new or newly painted rims, re-tighten the wheel nuts or wheel
bolts once again after approx. 1,000 to 5,000 km (600 miles to
3,000 miles).
For lay-ups or long periods of inactivity, keep the tyres and tyre bearings
free from pressure points:
Jack up the vehicle so that the wheels do not bear any load, or move the
vehicle every 4 weeks in such a way that the position of the wheels is
changed.
13.2
Tyre selection
The tyre sizes approved for the vehicle are given in the vehicle documents or
can be obtained from the authorised dealers or service centres. Each tyre
must fit the vehicle on which it will be driven. This applies to the external
dimensions (diameter, width), which are indicated with the standardised size
designations. In addition, the tyres must meet the requirements of the vehicle
with regard to weight and speed.
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.

A wrong tyre can damage the tyres during the journey and even cause
it to burst.

If tyres that are not approved for the vehicle are used, then the type
approval for the vehicle and subsequently the insurance coverage can
lapse. The authorised dealer or service centre will be happy to advise you.
