I have a '79 Ford with 2.5 ton rockwells and a set of tubeless 48x31x20 Goodyears, but no wheels. It is strictly an off-road vehicle, that will never see over 30mph, unfortunatetly sitting on 40" military tires (skinnies) and snap ring wheels currently. I am considering building my own wheels. I can get 20in pipe, so run 20in OD pipe (what ever width I decide, 22-24" or so) and weld the snap ring section of the military wheels to one side and weld a lip to the other side that I can bolt a flange to, basically a bead lock wheel. What do you guys think? Anybody ever done this? I figure it will cost me around $500-600 to build. 20in pipe is pretty expensive and I have to get it cut. A local machine shop can machine the lips and flanges for me, so they will be perfectly round. The tires are so stiff I doubt they will ever need much if any air pressure, and I can drill and tap a valve stem as well. The tires are rated for 26in wide wheels, but that is for co-op trucks and a 8000lb load, which the tires will never see, so I will make mine a little bit more narrow so I will never pop a bead (come off the wheel). The truck sees all terrains, but mainly mud and trails in my area. I would post pics but the truck isn't worthy yet. It is under a lot of construction..lol.
