Just put on Michelin PS2s over the standard 18" OEM Rims...
They are the Turbo standard tire sizes of 225/40/ZR18 and 295/30/ZR18...
For all of you running on PS2s (and I suspect that is quite a few of you) what are your ideal front and rear tire pressures?
Please post the pressures here and I can always tweak it a few PSI one way or another depending on my feel.
Thanks!

 

36/44 just like the OEM rubber. Of course, you may want to tweak from there as you say. I have no problem with the recommended pressure, but I also do not have OEM suspension or rims.

 

Wross is 100% correct (as far as I concerned..) I used to run 34/40 on the P-Zeros (and their stiff side walls) but with the PS2's I DEFINATELY run them at 36/44 otherwise it will feel floaty ay high speeds.

 

Above guys as usual are correct. But one thing I would add is if you go to a track event keep them hot at around 40 they really heat up and need to watch or they will be at 55!

 

I live in South Florida and have your set up, 36/44

 

I have oversize 235/315 PS2's. The seem to do fine with 31F 34R in everday street use.
