well I guess the PSI numbers would very it all depends upon what kind of tires you are running.

I think I will go 34 front and 31 or 32 rear.

I believe higher psi the better on dd better even tire wear. and gas miles.
I was running max 30psi on a032 adavans and man I shoudl have maxed teh psi out for better longer wear.
