I'm a rookie in the off road world... I use to track cars in my younger days but my research seems to show that 20psi should be pretty good for "airing Down" You can go lower like 10psi but to me its unclear if that's only with beadlock wheels and also our stock sidewall is SL rated so again question I'm looking to have anwered
Normally run 33 PSI for on road and 22 PSI for off road. I travel on a 62 mile dirt road with lots of washboarding, makes a super big difference. Helps out in the mud also
