So, On my front tires the channel that goes around the entire tire has the little bumps in it to show when u need new tires, well on the front those are even to the treads but on the back tires its not yet. So I'm guessing I need new tires, here's the issue, next weekend I'm going to Vermont with a buddy and we are of course taking the STi, So can I swap from front wheels to the back and back wheels to the front as long as i keep the left side tires on the left side and right on the right? Please help! (when I say wheels I mean the whole deal, I have no tire changing machine so I'd unbolt the front, unbolt the back, and swap. Suggestions please?
