I've had no rubbing at all and I have hit some BIG dips in the road at fairly high speeds. I'm not sure if 225's would fit. As it is right now the 215's sit VERY close to the fender well in the rear, I think 225's may rub in the back, but I'm not 100% on that. I also have the camber links installed, so that may have to be taken into account as well.
