sand driving...bogging down.
 
1 Attachment(s)
I tried driving in the sand today for the first time. I didn't get stuck but I couldn't get out of first gear. It would almost stall in second gear.

My tire pressure is around 30 pounds of pressure but I am not exactly sure because my cheap gauge broke on me. My tires are 31 10.5 15 mud tires.

do I need to air down?

The AC was put on full by my Fiancée when I was busy driving and not paying attention. Could that be some of it?

Any suggestions or thoughts?

Well first of all, there's no way you can drive on sand upside down, that's a no no.
Second lower the psi to like 12ish. Turn the ac off and pay attention to what you're doing so you can feel the wheelspin and stuff.

Jerry Bransford 07-22-2010 04:17 PM

Fully inflated tires offer a small footprint on the sand which means the tire will dig down into the sand more easily. So yes, you should air down to give the tire a bigger footprint which will help the tire stay up on top of the sand instead of digging down into the sand which could cause you to get stuck more easily.

I'd air down to 12-13 psi or so which will be a safe air pressure that won't cause the tire to unseat off the wheel. Carry an air compressor or stop at a gas station to refill the tires before getting back onto the highway. The max safe speed for an aired-down tire is only about 25 mph so have some means for refilling the tires before heading home. :)

Driving upside down might be an issue also. lol!
Airing down does help. For the sand dunes over in el paso im usually at 12 or 15psi for light trailing.
Also putting the transfer case into 4low helps when getting speed is an issue.
Are all 4 tires sinking? or just the rear?
Nice pic btw, where was it taken?

HeaveToo 07-22-2010 04:43 PM

Sorry it is upside down. My pressure was actually at 34 so I dropped it to 28 for highway drivi g. I may air down some more for the sand.

Picture is jus south of Rodanthe NC

03 RUBI 07-22-2010 04:55 PM

34# is too much for the highway under normal conditions. What do you mean "may air down more for the sand"? You asked a question and one of the best people on this forum answered it. Heed what he said.

HeaveToo 07-22-2010 05:20 PM

here is a cool shot if it is right side up.

I will ir down. I carry. Compressor in my jeep too. Good stuff.

Huh??

Btw Lethaljeep you put your rig in 4low in sand? Maybe I'm doing it wrong, I always use 4high for sand and 4low for steep rocky inclines.

I saw the pic and thought, "Mean while in Australia."

:rofl:

I just busted out laughing and spit my pepsi all over my computer. Thanks a lot! Now I have to clean it!

Friggin' hilarious. :D

I have nothing to contribute to this conversation, but learned alot from Jerry, et. al. I am planning my first sand ride in my TJ soon, and this gave me some good information. Thanks so much, guys!

Oh, and BTW...don't feel bad. I can't get my pics to show up right on the forum, either! :doh:

Just make sure that you're right side up.

:confused: What? I thought she could handle that! She IS a Jeep after all!

Still cleaning up my pepsi....:banghead:

Watch out for the wet soupy type of sand, it'll suck you in and it doesn't let go. Scary when the tide is starting to come in.

I will either be THE IDIOT on the 6o'clock news in that scenario, OR

the chick at the edge too scared to drive past the high tide line.

Just kidding. Thanks for the advice!! I need all I can get when it comes to off-road stuff. ;)

I drive in the sand all the time. I have 31x10.50 which I keep at 32lbs on the road and air down to 18lbs in the sand. The sand does slow you down. When the sand is real dry and deep, shifting to second gear is like putting on the brakes for a few seconds. I try to do my shifting when the sand isn't to deep or when in someone elses tire tracks. Last weekend I aired down and got half way to the water when I just started digging in, then I saw I forgot to get into 4wd. If I didn't air down I would have been in real trouble.

coolbreeze 07-22-2010 07:31 PM

A long time ago we ran 1100X15 farm implement tires at low pressure in the sand. (kind of looked like airplane tires) Traction tires aren't the best for deep sand. Have fun.

32lbs is too much for the steet and 18lbs is too much for the sand. How does one forget to put in the proper gearing when heading out to the sand?:confused:

My 97 4cyl with 31x10.50 bfg's has to be in 4low to go through the thick sand in NC. I tried in 4hi once and it bogged down so bad I thought I was going to burn the clutch up trying to get started again.

4low works like a dream through even the thickest sand with a 4cyl

The sand dunes we have in El Paso are very different from beach sand. The trails run in between Mesquite bushes, come around turns and up and down steep dunes. So sometimes its best, depending on what your trying to conqure with the speed allowed :D
Look up Red Sands El Paso, TX... there might be some pics

I was in a hurry to get on the beach and just forgot to it. It won't happen again. The state suggests 18lbs for riding on the beach.

And that 18 lbs is correct for every single possible vehicle and tire size? Hardly. Trust us, you're not even airing down if you're not below 15 psi for a Jeep.

lancetkenyon 07-23-2010 01:43 PM

Imperial Sand Dunes, CA. 3PSI rear, 4PSI front. 2wd only, never needed 4WD. Wheel speed and momentum are your friends.

I’ll reset my deflators to 15 and give it a try. In another thread the debate was if it was even necessary to air down at all. My friend has a YJ and has stopped airing down and so far has not gotten stock. What do you recommend the pressure should be for on the road?

Jerry Bransford 07-23-2010 02:56 PM

For 31" tires, 30-31 psi is fine for the street. For the sand, I'd take 'em down to 13.

That must be what the sand dunes in china look like:D

lol, you remind me of my grandpa when we discuss how well those deer whistles work and he says, "I haven't hit a deer since I installed them!"

But then other people are like, "They don't work at all! I hit 2 deer last year with them on my bumper!"

Both situations have the same outcome...with the deer whistles...their reliability depends on if you've hit a deer with them installed or not. With airing down, the answer depends on if you (or your friends) have gotten stuck or not without airing down. But the first time you get stuck, guess who will end up being right? ;)

Sandhills SC
 
Oh Yeah the fine baby powder sand we have here is some scary stuff it just shifts out from under you and you start to slide went on some of those roads first day I got my Jeep didn't get too wild but even in 4low you have to be very carful.This was the same road a guy was driving his truck on going a little fast hit some of this soft sand on the road edge filpped his truck he went out the window and the truck rolled over him and he died.

LATER,

Tommy

Guess it all depends on the texture of the sand. In Nag's Head, NC, the sand can be deep. If my jeep were an automatic I'd have no problem using 4hi, but since it's a stick and getting started is more difficult, 4low works much better.
