track tire press on 17s

[tsi_turboawd]

Next time i go to the track ill run with 17s(20lbs each) that i just got and see how it does. How much press should i run w/ my Pirelli 225/45s?

right now im running 39psi all around

I found my AWD launches best at the track on street pressure, about 35psi. If I had better tires (read: drag radials) I would lower it, but from my own experiences, street tires like street presure. Just experiment with pressures and see what works best for you. Good luck.

well I run 20psi w/ my 17's but Im FWD so that does make a difference.

yeah im FWD as well and I only had 15psi in my fron tires on 17s when I ran.. But I think I was a little low..

Dont forget i have AWD and running with wide 225/45/17*
PPL on the other thread posted talked about tire pressure on FWD.
would 35psi be fine on 225?

Start out at 32-35 & experiment from there... That way you find what works best for you & the way you drive. I run 235/45/17 Michelin XGT Z4s and when our track was really slick I found that lowing the pressure from 35 down to 20 psi got me .690 60' time... where as I was running .79x on the 35psi. Also realize that the tire pressure goes up as the tires are heated.. & cools when you come back into the lanes.
