The front tires are about 2% taller than the rears.
You need a 235/35/20 tire in the front ... Your current 2% difference in diameter will kill your x-drive system

Very unlikely.
X1 is a "front wheel driven" car with a transverse engine. It uses a LSD (limited slip differential) for the rear axle.

Edit. It's actually a Haldex LSD sitting at the rear axle.
