Trackday-only bike: street or DOT race tires?

[anthonyk]

Hey all, I'm taking a break from street riding for a while and turning my Aprilia back into a track-only bike. It has been a long while since I did a trackday, but I'm hoping to change that this year. I'm not fast by any means, but I'm hoping to pick up some speed as the summer progresses.

If you were going to put one set of tires on for a season of maybe 6 trackdays (more if I can swing it), would you put on DOT race tires, or street tires? I don't have tire warmers, though getting a set isn't totally out of the question. How much should I be worried about DOT tires and heat cycles?

All my trackdays thus far have been on street tires, so I'm not opposed to getting a set. I was just thinking I might take the opportunity to try something different.
