I searched but found nothing. So any the recommendations for driving my LWB Monty in the beach sand. Im running Bridgestone Desert Dueler Revo's(31X12.5) stock height, on bilsteins. Diff settings,tire pressures,etc. Thanks
You shouldn't need anything special...the most important thing is tire width, and you've got that covered. Lower the tire pressure a bit so the sidewalls bulge a little, and that's about all you can do. May wanna make sure your cv boots are solid. I hate driving in sand. Good luck!
4WD & as low a Tire Pressure as the rim will allow. I'd guess 15psi would be max. Any lower and you will have to be concerned with the tire slipping on the rim. The key here is to have as big a footprint as possible to prevent you from sinking in and even then it's always a possibility to have to contend with.
Keep your momentum going especially on any kind of upwards incline in sand. The moment you start to slow down or stop, your tires will start to dig into the sand. You want to avoid this. Of course driving this way, you need to know what's ahead of you on the other side of a dune so take care when doing this.
A shovel. Even one of the small folding military ones is fine.
A winch with a good anchor (another vehicle, pull pal, buried spare tire, etc.) is nice to have if you really get stuck. Sand ladders are another nice option to have especially if you do this frequently enough. You can buy them for as low as $150 for a pair of Smittybilts or pay more for other brands.
I've used a home built under vehicle wash 'device' made using PVC pipe and shaped kinda like a hockey stick... \_
The bottom is ~3' long and I perforated it with 1/8" holes so water can spray out. The top has a standard hose screw head so I could connect it to my garden hose.
I used that hose screw head which is attached to a short section of 3/4" ID pvc pipe 6-12" which in turn is connected to a 45 deg angle bend which is then connected to a longer section of pipe that again is connected to another 45 deg bend which is connected to the 3' long perforated section which is capped off. Total cost was <$20 and IMHO it works a whole lot better than putting a sprinkler underneath the vehicle.
^^ I built something very similar to what you're describing,used a bit of Qual-pex with holes in it bodged onto a hose fitting,worked really well until I reversed over it. I live about 5 minutes from the coast so I seem to end up on the beach more than I should. I drive into a river with it to get the worst off and then just ppowerwash it when i'm home
And something really important I should have put into my earlier post,don't reverse it in 2wd,you'll bury it up to it's tits in no time at all! I did it once,and it nearly ended badly.
Lower the tire pressure. I go to about 18 psi. Put it in 4 HiLoc. Unlocked rear diff. Just accelerate slow and you should be good to go. I never once came close to getting stuck. I used to drive mine on the beach almost every weekend when I was in NC. North End of Carolina Beach.... Oh how I miss it.
its not that the tires sidewall bulge that aids in floatation its the length of the footprint of the tire when aired down. So tall tires with plenty of rubber between the rim and tread are ideal, wide tires are kind of a wash between better floatation but they create a bigger "wave" of sand infront of the tire to overcome. Air down to around 15 psi and don't put yourself in a situation where you could get stuck in an area below the high tide mark. The only times I have seen anyone get stuck on the beach was because they were being lazy and did not air down, its literally as important as selecting 4WD.
One observation I have made from beach driving is that my engine and transmission temps are higher when in 4High so I recommend 4low. Once in 4Low temps return to normal, I think its easier on the vehicle but that could also depend on how soft the sand is.
Air down and coast to a stop, going very easy on the throttle helps not to dig in, and a scrap of lumber to put under a jack to keep it from sinking is also something that I always bring along. Other than that just about everything else has been covered.
