I can't do that. For me temps that high make the tire harder and doesn't have as much contact patch of the pavement. Guess a lot of this has to do with what type of alignment your running also. I have to have more flex in the sidewall. For me I get better feed back and predictablility.

too much body roll with 35psi, my lap timer was showing quicker laps with the higher pressure, my car is stock remember
