Tyre inflation

[DazzyA]

Can somebody please let me know what tyre pressure on a 325i cab, Bentley, haynes and owners manual all differ. The thing is my tyres seem to stick out from the rims as if they are not inflated enough. I've doing about 30 all round.
cheers.

30 front, 28 rear i think - but depends if you use allot on motorways or round town etc.

Only country lanes and a bit of town. That's ther strange thing as I thought the fronts would be more, but the manuals say more at the back!

Quite a few people on the zone opt for 2psi less on the rear, especially with uprated or lowered suspension when factory pressures go out the window. No good for drifting but great for roadholding and comfort. All a question of taste and trilal and error. Sounds like you have 225 tyres if they are 'sticking out' which will give more grip but also more roll if under inflated. If you are on standard wheels and tyres, either side of 30 psi should be fine. I'm running on 16" Alpinas with wider rears and use 30 front/32 rear.

Cheers monsport, exactly how the car handles, I thought that tyre size was spcific to wheel size
