15 PSI will probably cause you to lose a bead on your tires. If it's 12 inches or more of sand, on the RRS, going down no less than 25 PSI on stock tires, or 20 at most on oversize A/T tires is more than enough to get thru...I have been driving on sand beach with p38 for ten years now.Lots of fun! You won't be able to maintain much speed due to pedestrian traffic and other trucks. Use low range, air down to 15psi,and be sure to wash the underside when you return home. lawn sprinkler under the truck works great.
Managed to get an ML350 tragically stuck in the soft sand at Nobadeer in Nantucket a few weeks ago. Had to get down to nearly 10 psi to get out. Planning on giving it go in my RRS next. Will probably start at 20 psi and go from there.gravytrain, I see you have nyc as your location.I will assume you are going to nantucket or perhaps jersey shore. the sand in these locations is very soft. Your stock tires are adequate. you will not need to concern yourself with unseating a bead of a tire.I would again recommend 15psi, however you can always start higher and let air out if you feel a loss of traction. In nj you will find that the access roads to the beach are the softest sand because every truck that is on the beach has to access from these roads. I have pulled countless trucks from this due to overinflation of the tires.
This should give you an idea--not my clip just one I found. Its no South Padre Island. There are only a few beaches in NJ that allow year round driving, this being one. Never had my RRS on the beach but in my Toyota I have run street pressures just fine. Just don't be a maroon and make turtle holes.Not sure how deep the sand is there on the Jersey shore,
ARB bushranger x jack and a board most definitely. Full size spare and a shovel,snatch strap are bare essentials.good observation. yes, heading to nantucket in a few weeks. think i'll start with 20 then go from there if needed. do you think i should i have a board in the truck if needed?
thanks again for the advice.
You're required to have a board, shovel, and full sized spare in the car on the beach in Nantucket. It's not enforced per se, but if you do get into trouble you might have a problem.ARB bushranger x jack and a board most definitely. Full size spare and a shovel,snatch strap are bare essentials.
