Wheel matching is one of my kryptonites. I struggle getting my head around offset vs width and separately tires sizing and ultimately what will work togehter.

I'm starting to shop for a set of wheels / tires for the x3. It currently is on BMW style 279 wheels.

Basically, I'm trying to figure out if I can use 1er, e46 and/or e90 wheels on this thing.

They're 8*17 all around ET46 with a 72.5mm bore and a 5*120 bolt pattern.

Questions:
1. offset - how much flexibility do I have before I need a spacer? Is it better to go with a wheel with a higher value offset or smaller?

2. How do offset and width interact? IE: If I go to a 7.5" or 8.5" wheel, what do i need to do to the offset #

2. Didn't e46 x-drive cars have different offset compared to RWD cars? Did e90 cars have the same offset, or are they different too?


I found this chart and am trying to figure out what wheels I can use on this thing.
