Tires and sand/beach driving

Did a bit of searching, but didn't find the answer I was looking for. I have MFG M/T's on my Jeep, and I've never taken her on the beach before. With a fairly aggressive tread, do I really need to deflate my tires a bit to reduce my risk of losing traction?

15 PSI is a good rule of thumb in the sand. YMMV.

Don't hit a rock, 15 psi from what I hear is the minimum psi u should have before you break the bead on the tire, so I always go with 20.

Well, the tire bead safety is dependant on a lot of factors and they can be aired down to less than 5psi, but

If the driver has some experience/training in the proper driving/throttle techniques

Some of the variables in the bead safety are

1)-Wheel rim beadwidth

2)-Wheel diameter/tire diameter ratio

3)-tire loadclass A/B/C/D/E

4)-sidewall bias/radial ply layers

5)-steel or Alloy wheel

6)-Beadlocks or not (duh)

Lots a variables, including tire temperature !!

We go out on the beach fairly regularly. With 31" on stock rims, we air down to 12 or 13 lbs without any problems. Airing down makes a big difference in the soft powder sand on East Beach.
