For most of the X3 OEM tire configurations (except the 225/60R17 tires), the pressures should be higher for the rear tires. Most dealerships don't seem to pay any attention to that and have been known to typically deliver X3s with tire pressures all over the map. For the 245/50R18s, 35F and 38R work pretty well.

It's such an easy thing to check, and is often completely overlooked. A left/right difference could certainly create a steering bias.
On my car with 245/50 18 the advice is 2.0 / 2.0 bar which is 29 PSI. I'm running 2.2bar / 32 PSI currently. Sounds like I should experiment with some more air.
