How can you run your tires at a cold 35/36 on a track day?
My PS2s need to drop down to 20-22 cold psi to keep them below 40-42 hot psi on track runs.
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... |
I track at the Nurburgring and take 20-30min breaks between laps. Also, weather temp makes a difference (45-50 the last two times). The pressure went up to 44 after 4 laps during my last visit; that was the highest.
