Sand Dunes - Tire Pressure?

[SamG]

Hey Y'all

I've already ran my Bronco through its paces in the mud/dirt/rocks at Holly Oaks Off Road Park.
I plan on taking Friday off and day-tripping to Silver Lake Sand Dunes.

Suggestions on tire pressure? Some sites suggest all the way down to 10 psi, others are saying 20 psi... quite the variance.

Any ideas?

20 is sufficient.

Make sure to post your trip report in Michigan Bronco Club. I'd like to go someday when the horse arrives in the stable.

It really depends on the type of tire, size of the tires and wheels, weight of the vehicle, and the type of driving.

For me, the fear isn't so much losing the bead, but actually pinching the sidewall. So in the faster stuff, more air is called for. If you're driving pretty gentle, then you can go much lower.

In my experience, you can't even call anything over 20psi airing down. All the magic really starts below that. For straight traction and flotation, lower is better.

I would start at 20, then drop a few PSI if needed until you find the sweet spot and gain confidence. If you get stuck, don't be scared to air way down into the single digits help get unstuck. On my EB with 36x12.50R15, I'd run 10-12psi. In the snow I run 2-4psi.

I would say start at 18psi and see how it goes for you. It's easy to let out air if you need too. 10 seems too low unless you are just cruising a beach.

It depends on the sand.

As others have said... 18-20 PSI is usually just fine for the usual typical sand... but if you have really fine sand (like in Sand Hollow in southern Utah) I've had to go down to 9 PSI before it get anywhere.
