Hello, I want to take my Cayenne on the beach but I have a few questions.
1- what PSI should the tires be at?
2- Should I use the diffs?
3- If so, how do I use the diffs? LOL
4- anything to watch out for?

Thank you guys.
Ps I don't have air suspension.

 

What size wheels do you have? I would drop the tire pressure a little but not like I would a bigger truck tire. I would take it easy depending on how soft the sand is. But I think you will be fine for the most part.

 

I have 18inch, I read some where to drop it down to 30PSI. I just really don't want to get stuck because I don't have a beach permit and I'ma do it anyway.

 

You can put the transfer case in low first (first setting). Then the other option is to lock the center diff which will even out the power front and rear. On the older models I don't think you can lock the rear unless it was an option on the special off road tech package.

 

But like I don't have to lock them right? I can just lower the tire pressure?

 

I am certainly not an expert but I would think locking the center is probably not a bad idea. It evens the power out between front and rear to 50/50 from whatever it usually is, something like 68rear/32front.

Think of it like a 4x4 truck, which it really is. Normal driving you are always in 4-high. The first flick of the switch puts it in 4-low. The second flick locks the center diff like I mentioned above.

 

When i attempted dune bashing, i dropped my tyre pressure to 20psi (i have 20" wheels). I think i managed about 300 meters before it got stuck on a dune. It was a fun 300 meters though

I was speaking to the specialist i use a few days later and he said the Cayenne isn't really build for use on sand - the Nissan Patrol and Toyota Land Cruiser are good for this purpose. If the sand is a bit hard you should be ok. I haven't attempted it again but I was told to lock the center diff when driving on sand

 

Hmm, Ok so I will lock the center diff. So what PSI should I do? 20 or 30?

 

Who wants to take bets how far I will get before I get stuck? LMAO

 

What PSI do you normally run? There was a guy with a purpose built Toyota Tundra with offroad tyres and offroad suspension and he was running 20psi in that and recommended me to run 20psi also. He had a much smaller wheel rim (maybe 16"?) but really fat tyres. I'd run 20psi, but don't blame me if you get stuck

 

What sort of sand is it? If it's dry dune type sand I'd be willing to bet you don't get more than 1/4 mile. If it's packed wet sand you could probably drive all day.

 

I agree with the above. Soft is going to equal a short day of driving and a long day of digging.

 

At the beach in Cape Cod I go to there is a offroad area in the sand and there is a sign stating to lower pressure to 18 psi. Also smart to bring a shovel and piece of plywood or carpeting if you get stuck.

 

Havent checked my PSI, so I'm not what I'm currently running.

The sand is dune sand, It gets wet and packed closer to the water. I'll deff bring a shovel. Should be a funny trip.
so 1/4 is bet number one LMAO

 

Without air suspension and the tire inflator how do you plan to get the tires back up to normal pressure? I sure wouldn't want to drive very far on the road on tires at 18-20psi. And if you do be sure to take any corners very gently so you don't roll the tire right off the rim.


Might be worth grabbing a cheap little compressor that plugs into the lighter.
