if you want u can even drop tire psi lower to like 10psi, before i had 4x4 i drove on 8psi and never popped a bead, just always look for soft spots and try to avoid them, if u cant, just dont let up on the gas till u feel urself on harder sand, i tow my toyhauler to glamis and gordons all the time soo i know what im talking about, and if u do get stuck, Stop, grab u sholve and start schnigN and get all the sand away from the low spots, and around tires, and wood will work nice to wedge under tires to get traction, other wise have fun, and the water is damn cold still, bring a wet suit
and bring alot of WD40 to spray down bare metal, cuz that salt water does wonders,
