Interesting, I've seen ads for that stuff in GRM and other places and always kinda suspected it was a gimmick. Do you have experience with it? What compounds does it improve? (I was guessing it couldn't save true slicks that had 20 HC's and would be pointless on normal street tires?)

OP: I wouldn't shave used tires. In my experience RA1's got fastest right before cording though, don't remember heat cycles being an issue.
