I've played around a little bit and have gone from 8 to 14 on 15x30 mongrels and like trukinrzr I prefer around 12 for high speed stability. I have cut a sidewall at 14 but don't know if that would have happened anyway. Great grip on the rocks as well at that pressure.

Around 10 psi, + or - would be a good starting point, for sure
