The best traction on most tires is acheived by running the lowest pressure at which the tire won't roll over onto the sidewall during cornering.

With our V710 autocross tires (245/35/18 front, 285/30/18 rear) we run 30psi front / rear on medium traction surfaces. Couple psi higher if it's a high traction surface and a psi lower if low traction.
