| This is what I see in my 2003 owners manual:
Tire size: normal / Max load
Front-225/40 ZR 18 32 / 39
Rear -255/35 ZR 18 38 / 46
Looks like you can download the 2005 330i owners manual from BMW USA:
It lists slightly different pressures and includes pressures for speeds > 100 MPH
Also if your tires are SL (standard Load) or XL (extra load) will effect the max load tire pressure the tire supports. (not the max inflation pressure on the side of the tire)
