Track question

[mitsuclipsegsx]

I am going for my first time this Wed, and was wondering what tire pressure i should run. I searched and just found so many different answers. i run 225/40/18, 20psi good?

thanks

I would start at 30 and go from there, 20 is the lowest i've ever gone in my search for traction.
