My guess is it is your tires, not placos tires, your tires. but, what do I know.
nono, i completely agree with you. It is definately something wrong with my car, and COULD be my tires. I was just stating the fact that the tire size shouldn't be the problem, though as you are saying it helps cause problems.
I'm going to try and do measurements between wheels and see what I come up with, thanks guys, all this is really helping.
