Checking to see if 215/40/18 would fit on a xB

 

Yes, but I recommend 225/35/18 on a 7 1/2 wheel. Will actually give you some wheel protection, but this tire is more expensive and not common. Nitto 555 and Toyo Proxy makes these and I have tried both. This tire size will save you some grief w/ curb rash and pot holes. I have a 2" drop.

 

would 225/40/18 be to much

 

That's what I have... It rubs just slightly at full turn, but it fits.

Thanks alot THE_DON. I might be getting some diablo wheels with some tanabe springs so I wanted something that will protect me more. If it rubs I can always shave the wheel well or do some modifications.

 

I shaved some of the plastic under there to help... Just know, the lower you drop your car, the more it will rub. At stock height it almost didn't rub at all. On Hotchkis springs (1.6" drop) it rubbed more. If you went really low (like tanabe DF210) it might be too much. Some spacer might help, too.

Good luck
