I ran them at a cold 26-28 psi last year and tested to a scary 52 psi after two 20 minute track sessions on a mild day (60 degrees f).

If I would have started at 35, I would have well exceeded the maximum pressure and probably experienced a blowout assuming I didn't lose it from lack of grip...
You wouldn't have this problem if you used nitrogen rather than air. My dealer filled the tires with nitrogen for free, didn't even have to ask.
