First off, I have new, sub 10,000 mile, $500 Michelin Hydroedge tires on my car. They were expensive, but man, do they work great, on anything. My only gripe about them is that they wander a bit and they pick up stones like a mutha. I drive my car hard to begin with (outside of the tread is showing a little wear line), but I'm worried about tire wear, specifically the outsides of the tread if I were to autocross on these... Thy're a hard compound, I can chirp them pretty easily taking off from a light, but I dont want to rip the crap out of them in one day. I dont have money for an extra set of tires, or I would do that... Any thoughts/Suggestions?
