I'm looking to get some slicks and 15" rims for the track, and want to know the biggest size I can run without rubbing. I was hoping for a 10.5" slick, but don't know if I can do that. I'd appreciate any info anyone has regarding a good rim width/backspacing, and slick size. Someone mentioned a 26" slick on a 9" rim with 5.5 BS would fit perfect, but I'd rather hear what you guys have to say. I don't much care for what it looks like, so long as it fits, doesn't rub, and hooks like a dirty mother.
