Help!
Has anyone got the definitive tyre pressures for g29 20i? The door post sticker, the handbook and a phone call to the dealer are all different!!!
Many thanks

I set mine at 2.2 bar all round which is what it says on the door plate. This also corresponds to what iDrive thinks the correct pressures are for my tyres.

I also set my tyre pressures the same as dr_john 2.2 bar or 32 psi

you can check in the car settings thing, you can see the pressure for different types of driving and the different tire sizes.

the dealer does 2.2 bar by default (I think its the same as stated on the door sticker), but the settings in the car go up to 2.8bar if you want eco driving 2.6 for top speed runs and 2.3-2.4 for normal load runs (also the numbers change depending on the outside temperature there)

My idrive says 2.3 bar all round which is also on the door sticker

Car says 2.8 bar recommended for my tyres and I keep it that way on summer tyres. It changes even to 3.0 bar when tyres are hotter.

Just checked mine, Idrive asking for 2.3

Or it was, now that that they are set and a short drive, asking for 2.2

I'm running at 2.3 bar which seems good for all round and gives me around 46 MPG on motorway runs (ACPO guidelines) on cruise control.
