I am going 5 front and rear on the Beta Rev 3 270 trials scooter. You can bring it over here and launch her in the pasture to experiment. I could loan you my CO2 tank for your trip?

I know I am in the minority but on my 525 with D606s I run 15psi for off road only. For stuff where I'm running pavement I go to 20psi front and 20-25psi rear depending if I have my camping stuff or not. I let my suspension be the cushion. I don't think any increase in traction is worth damaging a rim or tire in a remote location. YMMV

sometimes us minority folks are the wisest.

Besides the points you made above, riding in rocky terrain is just asking for a pinch flat unless you ride at crawling speeds. I like to ride more and patch/replace tubes at trail side less. Maybe a racer needs the advantage a 5 psi reduction brings but for dual sport nobody does.

The only reason I have 15psi in the front is because my tube has a slow leak!

For big bend, my buddy on his XR650r and me on my xr400, we both use 18psi rr, 19-20 fr., on 21"/18" spokes
he uses desert maxxis iT fr&rr,
i use combo d606 rr , mt21 fr

This PSI range is the best compromise for a dirt bike doing big bend as this ensures no pinch flats should you hit that sharp edge riding the canyons at a good clip, and it ensures you don't melt up all those sweet knobs pounding pavement to the nearest gas station and/or back to your motel/campsite.

Perfect info, thanks!

Rear 606 is a stiff tire to begin with but they still do bad things at low pressure. I saw one with its bead cut from hitting the rim in rocky terrain... sort of a pinch flat on steroids. The guy was running some ridiculously low pressure at the time and we weren't really floggin it up that mountain. Go with the suggestions offered above.
