This is the most basic question in the world, but I'm not finding a direct answer with a search of the forum (could easily be my searching skills), but I would sure appreciate input.

I'm running my 2008 GT2 on the track this weekend on the OEM MPSC tires and am wondering what I should aim for as a hot tire pressure front and rear.

Thanks!

 

Michelin's guide for MPSC is +4 PSI hot above what the cold temp is.

So for my GT3, cold settings are F - 29, R - 31. Hot and at the track I therefore run them at 33 and 35. Works well!

 

On my OEM 19" MPSC:

22 cold all the way around to start works for me.

32 front and 36 rear hot is the max i usually go.

 

From Michelin: http://www.tirerack.com/tires/tirete...nd_Feeding.pdf

Hot front/rear: 32psi/36psi
Camber: -1.5 to -3.0
Temps: 160 - 220F

 

Hey guys... Thanks so much for the quick and helpful responses. Looks like I'll be targeting 32/36.

 

I have a 997 GT2 which I track a lot. I find that 33 front and 35 rear hot works very well. I usually start the day at 25/27cold and have to bleed some air after the first run group and later in the day as the temperature picks up. Good luck on your track day. Remember to get the car pretty straight before mashing the gas.
