so, Rosco and others, one thing that keeps me from getting 255s is the fear that they are not as good in the sand as the 285 cuz skinnier. I would think it's undisputable that wider is better in sand. Yet, you don't seem to think the 255s suffer from that? Care to elaborate a bit?

This has been tested a few times in oz.
As a tyre deflates ,it gets longer not wider.
The wider tyre will have slightly more flotation but its not noticeable as far as traction goes
I have 235x85x16 and they go anywhere my old 33x10.5x15 BFG A/T did without the onroad rolling resistance.
I think having the right tread is more imporrtant than anything else.
Having big lugs ,especially on the side of the tread,is a big no no in the sand.
You want to be rolling across the sand ,not churning it like a bucket shovel

I got stuck on a beach recently,on my own with the camper on the back,stupid I know.
I let the 235s down to 10psi and it walked up a steep shoreline like it had legs

Im talking about soft sand driving as that is what I mainly do.

There seems to be a consensus for "tall skinny" tires in the expedition portal forum site. In my mind, the quintessential example of "tall skinny" is the 235/85R16 size. Any thoughts on this size?

235/85R16 is skinny...but...not as tall as 255/85r16

taller is better ....if you dont want to bang up the bottom as much off road

My 40 came with a set of bfg at's on it with plenty of tread. They were stock size. First time out with the truck i was pretty disappointed in thick mud (high clay content), as the at's turned into racing slicks. I promptly put my 33" bfg km1's on and have never looked back. I've put over 30,000km on them, never had a puncture. Half of those km were on my 62. Havn't wheeled that much in sand with them, but they work great in snow when aired down. I'm often the only one in the parking lot at a local backcountry entrance point without chains on when the snow is thick. Done quite a bit of crawling over rocks as well with no complaints.
