There are many posts regarding different wheels. Can we discuss what the Pros/Cons of moving from 10 wheels to 6 wheels. Is there a benefit of flipping the hubs and running 9 x 20 wheels in a 6 configuration?
Well (from what I understand) the trucks came stock with 6 1100r20s. Then the government went to 10-900r20s. I like the look of duals so thats what I'll stick with. It makes the trucks not want to turn though. It also creates alot of bind with that much traction on the rears.
Singling the truck out will result in better fuel economy (because of the larger tires), higher road speed, better off-road traction and less drag on pavement as GIMPYROBB says. David Doyle has written about single vs. dual wheel performance.

Not completely accurate. The "Deuce" was originally made in three variants, the M34, M35 and M36. The M34 "Eager Beaver" had 11:00-20 tires all around, single rears, and a narrower bed (because of the narrower overall tire width) with wheel wells (similar to the earlier M135s, to allow for suspension travel with the taller tires). The M35 had 9:00-20s all around, dual rear wheels, and a wider, flat cargo bed. The M36 was a long wheelbase version of the M35.
The M34 was preferred for off-road use as the single rear wheels provided better performance in mud, snow and sand. The M35 with its dual rear wheels was designed primarily for on road use and its wider, flat bed was better for carrying cargo. Eventually the M34 was phased out in favor of the M35.
Now for the rest of the story. Sometime in the '80s-'90s, the military remembered the advantages of single rear tires, and began retrofitting older vehicles and building new vehicles with "super single" rears in 12:50, 14:50, 15:50 and 16:00 tire sizes to regain the superior off and on road performance of the single rears without compromising cargo capacity.
This is great, many good pieces of information. It really is making me lean towards moving towards singles on my 9 x 20's until I can find larger ones near by. Right now, my duece has 6 brand new tires and 4 old ones it makes sense to go to singles. I live close to Oceano Dunes and would like to use the duece as a camping vehicle for the beach.
I don't think anyone here is suggesting single 9.00x20. You should stay with duals if you are running 9.00x20s. Only go singles if you have 11x20s or go super singles if you have 14.5s or 15.5s.
