means of a tyre pressure sensor.
The tyre pressure and the tyre temp erature
appear in the driver's displa y.
If th ere is a substantial pressure loss or if the tyre

R front wheels wear more on the tyre shoulder
R rear wheels wear more in the centre of the
tyre
Do not drive with tyres that ha vetoo little tread

ro ads (aquaplaning).
On vehicles with the same front and rear wheel
size, you can inter change the wheels every
