I have maybe 5-6mm of clearance on the inside to the coilover springs, and about the same in the rear before it touches the lower arm.

255/45/17 would have been ideal without any stretch.
I can notice it a little bit on mine, with the 245's but they are a more common tire, incase I get a flat, and I need something in a hurry. And I think I am maxed out for clearance anyways.

225-235's on a 9inch i think is getting into VW territory.
