Good info, yes I did deflate to around 15 to 18 psi around. The truck does fine in the normal beach sand its the stuff in the last pic. You can see my tracks trying to get back onto the tidal level area. Soon as the sand gets around 2- 2 1/2 deep the truck just slugs and stops and wheels start to spin. I will get better pic's on sunday , the deep sandy hills are what kill me. Getting down to the beach is prolly a 250 foot cliff trail that was carved out by a river, towards the end the beach sand over the years blows up the area , easy going down, hard going up. Damn Toyotas are going thru stuff like its cake and im stuck. LOL I already planned tires and a small lift, do you think I should wait and see how they work for me before I look into diffs?
