Don't try to save money on tires, especially when you are new to racing. An experienced rider may feel the tires going away, but few new riders have that ability. I'm not saying you don't have a feel for riding, but think about this; if you try to save a couple bucks by running a set of tires just one more time and crash, then what? You then pay for bike repairs, maybe some minor medical bills, and you still have to buy that new set of tires.
I know from experience. This year I expect to replace tires probably more often than needed; however, as I learn to feel them I can get a bit more wear and tear.
BTW I crashed on cold medium Michelins. Still use Michelins though.
