What pressure are you all running on your s03's?

I have 225/45/17 front and 245/40/17 rear on ssr gt1's 17x7.5 and 17x8


I've tried 30psi up to 38 psi

So far these tires are squirmish like hell.... Im have close to 500 miles on them. Hope over time these tires "stiffen" up...

Speaking for James and I, we run 36psi front and 32psi for street. As temps fall here in the area, the tires will definitely feel more squirmish. We would recommend switching to winter performance tires (we both have Michelin Alpins for the winter). You'll lose handling but gain reliability and stability in cold weather conditions, which can get pretty dicey with the SO2s/3s and other brands of ultra high performance tires in temps below about 50 degrees.

Well, its not the lack of traction/grip i am complaining about. The sidewalls seem to flex alot more than the oem S02s.

It seems strange as the 17 in tires have a lower profile than the oem 16 inchers.
