What problems will i face?
Agree with Giz. While 19s will fit, you have 1 major prob:
Our roads - hit a pothole or any major imperfection and it's off to the tyre shop to replace a tyre, redo alignment, straigten a rim, etc, etc..
IMO, unless you actually have to drive the car, 18s is the biggest I would go on the E46 given the current state of our roads.
