Nebraska Tire http://www.nebraskatire.com/truck/overstocks.htm still sells 8.25 tires and they mount them. Most farming area tire shops still mount them. Tube required wheels are still being produced. I started switching my fleet to tubeless back in the 70's because they are the way to go with a fleet. However, I still use tube required tires on my old jalopies and there isn't anything wrong with them. I don't let the younger guys in my shop mess with them because they expect everything to be idiot proof. I have been told that multi-piece wheels are illegal, but no one has ever has been able to show me such a regulation. But it sounds better than admitting that they are too dumb to change them. I think it would be a real shame to put tubeless tires on an original military vehicle.
