    37" BFG KO2s = 36 +/- OD
    8.5" x 17" SVT Bead lock wheels

    38 - 40 PSI Hot - Towing & not towing - Majority of dirt roads, Light snow and pavement.
    10-15 Hot - Sand, mud and snow more than 10"
    Works well accept for clay type mud which I blame on the tire design - They weren't made for that type of utilization.

    My Boat weighs 7000 +/- Lbs with gear and people

    I've stopped airing down. There are two reasons to do so, traction and comfort. I'm not crawling my Raptor. The biggest obstacles I'm climbing over are about a foot tall. If the terrain is wet, then I might air down since the K02s are ATs and not MTs.

    When it comes to comfort, I played around the different modes and found that if I'm in 4H, I should just leave the driving mode in Comfort. I will go to Baja if I'm going to go faster than 20mph on a trail. I have yet to have a real need for the crawl mode.

    Running Toyo 35x12.5r17 AT2's which call for 55 psi for street pressure to match the factory according their load index. I run 42psi on the street, air down to 28-30 hot for offroad, and 18 for sand dunes.

    If its sshort offroad trip (like, a just a few miles to go shooting or something) or a smoth gravel road, I don't bother with airing down.

    30 in the front & 28 in the rear (wanted a more firm steer feel) -Gen1 down in Baja. A lot of guys were going down to 25 or lower, I personally was not comfortable with that cause although you have the occasional sandy wash's & soft hill climbs (which the truck did just fine) the next thing you know you're sliding around turns throttle steering and hitting straightaways doing 80 to 100 and that's not cool on aired down tires! My Gen 2 has only been local wheeling around like at King Of Hammers which I did not air down at all and no problems.
