Only use tyres approved for the wheel rim type fitted. The permitted rim
and tyre sizes are quoted in the vehicle documents and the authorised
dealer or service centre will always be glad to give you advice.
Run-in new tyres for approx. 100 km (60 miles) at low speed since only
then do they reach full strength.
Fig. 229 Tightening the wheel nuts
or wheel bolts cross-wise
Tighten the wheel nuts or wheel bolts in the order shown in Fig. 229. In
order to do this, use a torque wrench and comply with the specified
tightening torque (see section 13.5.2).
Check regularly that the wheel nuts or wheel bolts are firmly seated. Re-
tighten the wheel nuts or wheel bolts of a changed wheel after 50 km
(30 miles). While doing so, proceed in the order shown in Fig. 229.
When using new or newly painted rims, re-tighten the wheel nuts or
wheel bolts once again after approx. 1,000 to 5000 km (600 miles to
3,000 miles). While doing so, proceed in the order shown in Fig. 229.
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
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 ap-
proval for the vehicle and subsequently the insurance coverage can
lapse. The authorised dealer or service centre will be happy to advise
you.
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 di-
mensions (diameter, width), which are indicated with the standardised size
designations. In addition, the tyres must meet the requirements of the vehi-
cle with regard to weight and speed.
