Thanks Andrmorr. I haven't updated the thread. I understand what you are saying. I'm a descent welder and could do it myself. I have access to a roll also.
But I bid and got some Hutchinson rubber ones. Ill go get numbers and dimensions.
Okay, they are; Hutchinson 20x11 with a number AMG RCSK15406. I think they are for the M35A3 wheels, but not sure. They measure 10" wide so should work perfect for my wheel/tire project. And I have 2 A3's at the moment, hoping to move one.
Here is the rim that combining the two wheels makes (photo). I have 4 of them at the machine shop to fit the o-ring, machining the outer ring about 1/4" shorter. I'm short of cash because I purchased an M929A2 (and its coming today), so am not pushing the wheel project ahead yet. These sand trails with chains (which I have) should make a combination to float, but dig in too.
I notice your 930 has troop seats. So does mine and no scratches in the bed, if the photo's didn't hide them. One seat and the cover were in the bed. Has 8968 miles. Here is a couple photos.
