Thanks for the input.I bought a set of 16/33s got a good deal on them I wasen't sure about them. I ran them the last two weekends and they seem ok. Still havent found the psi I like. My rebound was to soft and think the body was lifting to high. So it spun a little bid will see next sunday? other wise i like them. 6 PSI seems low I've gone as low as 6 3/4
