I currently have stock 225/60/15 tireson- What is the biggest sixe up to go without any mods- How much does it raise the car if at all

oops

I'll guess it's an '01 Outback Wagon. We don't have any larger recommendations than stock. I'd wait for some Outback guys to look at your post because I know there are some "unlisted" options, like possibly 235/60 or 225/65 etc. I just can't guarantee larger sizes because we're unable to test them and it gets pretty close under those fenders.

My 97 outback went 1 up with 225/16 on Koseis at Tirerack's recommndation and they rubbed on the INSIDE against the shock tubes. It was a major pain to get spacers machined to offset the tires out away from the shock tubes, but that worked fine.

You gotta realize that as the Outback is raised in height, the shock tubes move more outboard and closer to the inboard side of the tire sidewalls. Tires that fit on the Legacy wagon may not fit on the Outback!!
