Wheels with alloy rims are changed in the same way as wheels with steel
rims (see section 13.5.3).
13.6 Spare
wheel
support
The spare wheel is in the rear storage space or in the rear garage.
Fig. 232 Spare wheel in the rear
storage space
Loosen the wing nut (Fig. 232,1) and unscrew it.
Remove the pad (Fig. 232,2).
Remove the spare wheel.
13.7 Tyre
pressure
Tyres overheat if the tyre pressure is too low. This can cause serious
tyre damage.
Check tyre pressure before a journey or every 2 weeks. Wrong tyre
pressure causes excessive wear and can lead to damage or even to
tyre burst. You can lose control of the vehicle.
Use only valves that are approved for the specified tyre pressure.
Check the tyre pressure on cold tyres. Do not reduce the higher tyre
pressure when the tyres are warm.
The payload and the durability of tyres is directly dependent on the tyre
pressure. Air is a volatile medium. It is unavoidable that it will escape from
tyres.
As a rule of thumb it can be assumed that a filled tyre loses pressure at a
rate of 0.1 bar every two months. To prevent the tyres becoming damaged
or burst, check the tyre pressure regularly.
The information on pressure levels is valid for cold tyres and loaded ve-
hicles.
Pressure in hot tyres must be 0.3 bar higher than in cold tyres. Recheck
the pressure when the tyres are cold.
The valve used must be approved for the air pressure. We recommend
the use of a metal valve for pressures greater than 4.75 bar.
The tyre pressure tolerance is +/- 0.05 bar.
Refer to the vehicle documents for the maximum permissible axle loads.
