Hey everyone.... Yesterday I did go again to the beach and I deflated my tyres and boy was it different from the last two times!!
I deflated the tyres to 20 psi (I thought I would start with 2o and if needed I could go down to 15 just in case I needed it). 20 psi worked like a charm. My wheels are 245/65R18 and with the 20psi pressure I was floating on the sand and not inside as in the last two times!
It is an amazing feeling to go to the same spot where I got bogged before and I could just float on top of the sand. I took with me the battery operated 2 pump compressor and I managed to re-inflate the 4 tyres in about 10 minutes. So it worked well after all.
Looking forward to the next trip, and maybe I should deflate them to 15 just to see if there is any difference from the 20 psi!!
A couple of points to think about driving in the sand with a "car" - rather than a 4X4...
Dropping the tire pressure is the number one thing (as you just learned) to not getting stuck in the sand. 15 PSI really is the magic number - but one thing to be very careful of (well 2-3 actually) - once you drop the pressure, no higher speed corners or you risk peeling the tire off the bead, and then (no damage) you have a flat tire.
No driving (at any speed) on pavement with tire pressure that low!
No matter how long it takes, air up the tires to around 30 PSI when done playing (no sense trying to get them spot on when warm/hot, simply get them close, go home, in the morning when cold set them to your preferred PSI).
As for tips in the sand...
A fold-able shovel, a cheap "come-a-long" and 30FT of steel 1/4" cable - and if you get really stuck, you simply bury your *fake* spare tire in the sand with the shovel, use the come-a-long to move your Veracruz 6' at a time, and in bout 40 minutes you will be unstuck! if you are mudding in the woods, a handy tree replaces the buried spare tire (used to play with a 59 bug out in Oregon - my come-a-long, 30' of cable - could go just bout anywhere...LOL)
Last point. Sand driving *is* fun. But I bet your favorite mechanic could tell you 2-3 great reasons why you do not want to do that often with your nice new 40K car - sand is very tough on bits and pieces...
