I've heard some advise to not go below 35psi with the Bridgestones. I ended up with low 30's front and high 20's rear but again, everyone (and every surface) is different - gotta experiment for your sitution to find what's best.

38/35 seems like a safe starting point.

To me, the Bridgestones are head-and-shoulders above everything that was already out - R1R, RS3v2, Z2*spec, etc. However there's still the BFG Rival-S and Kumho 720 to learn about - the former has started shipping and the latter is supposed to this month.

What j-rho said about pressures being car/setup specific.

On the 350 STU car we have 275s mounted on 11" wheels with -4° camber, so obviously a different situation compared to the same tire mounted on a 9" wheel with -.7° camber. We were running 30 PSI and weren't even getting close to the arrows/triangles on the sidewall.
