Can aggressive driving wear inside edges?
After three days of fun in the Texas hill country this weekend, I found my inside edges had been pealed away to the cords on both tires. Yea! It scared me when I saw what my life had been riding on. I know inside edge wear is typical for vettes. My first set of tires did this, so I had the alignment changed to -.7 camber, 7.7 caster, .02 toe to help reduce the problem.
This time was very different. The tires (275 35 18 PS2) had been wearing evenly with no excessive wear on the inside edges. I was very pleased with the wear pattern. They still measure even wear except for the inside 1 inch which is litterally torn away. I'm inclined to stay with the same alignment spec but want to understand what happen this weekend. I would have thought the outside edges would have shown more wear, not the inside edges. Any ideas what might have happened? Its getting new tires and the front end checked out tomorrow.

Aggressive corning will wear the outside edges of the tire, not the inside. Toe in will cause inside edge wear. A lot of negative camber can also cause some inside edge wear. My guess is that the toe in caused your wear and not the weekend cornering. You didn't mention how many total miles on your tires.
If you plan to do a lot of aggressive driving, I'd follow the alignment recommendations of Phadt Engineering that you can find here in the Forum. I chose to go fairly aggressive on my car with -1.5 degrees font camber and 0.0 toe in with -1.0 degrees rear camber and 0.06" total toe in. I've done some autocrossing and and a HPDE day with my OEM tires and they are wearing quite well.
