I like to run hot 36/38 front/back on that same tire, I can't find my sheets from last October dang it but when I get the tire pressures right the car really feels good and it corresponds with my best times. Getting over 40 and it gets really greasy, and too low and you run over the sidewall marker and running low can cause more friction and (i heard) can oddly cause your tears really to overheat and increase pressure and make you think.you need to bleed more. I made that mistake before
