Hi All,

I had the tyre pressure warning come on this morning and am hoping its just a slight drop in pressure that has triggered it! I'm not sure what pressure I am supposed to put in my tyres, so hoping you experts can put me on the right track!

My tyres are RFT Pirelli P-Zeros on a 335I coupe are as follows:-

Front : 225/35 R19
Rear : 255/30 R19

Also - how do I reset the pressure sensor !?

Any help as always appreciated..

Thanks

Tyre pressures will be on the black sticker visible when the driver's door is open.

Unladen pressures for mine with same tyre sizes are: 2.6 bar front, 3.0 bar rear. Check your sticker though!

Tyre pressure sensor is reset via iDrive. Ignition on. Select: Vehicle Settings > Vehicle Status > Init Tyre Pressure Monitor. Start driving.

38 for the fronts and 42 for the rears...

or 36 and 42....

you need at least 42 at the rears...otherwise you'll get uneven wear...

If the drop is enough for the tpws light to come on, then you have a slow puncture.

I run the same pressures as above.....
