Chapter 4: Wheels and Tyres
4.1 Wheels
The following applies for tyre bolts
If you are driving a new vehicle, or after changing a tyre,
tighten the wheel bolts or nuts after you have driven the first
50 km and then again after the following 100 km. For your
safety, do not use any tyres or fixing material other than what
was originally stipulated. Wheel bolts and nuts should then
be checked regularly to ensure that they fit tightly.

Tubeless tyres have been mounted on your HOBBY motor
home. Under no circumstances may tubes be inserted in
these tyres!
Winter tyres are mandatory in many EU countries!
If you are driving in snow, ice or sludge in one of these
countries, your vehicle must be fitted with tyres that have
the "M+S" symbol. You may be fined if you ignore this
legal requirement.
4.2 Tyres
Use only tyres that have been entered in the vehicle's
documents. Other tyre sizes may only be used if they have been
permitted by the manufacturer of the basic vehicle.
• Check tyres regularly to ensure that the tread is worn
down evenly; check tread depth; check for external
damages.
• Always use the same make and model of tyres (summer
or winter tyres).
• Drive carefully on new tyres for a stretch of approx.
100 km to enable them to develop a full road grip.
Driving to protect your tyres
• Avoid braking sharply and racing starts.
• Avoid long drives on poor roads.
• Never drive an overloaded vehicle.
