Lots of misinformation and outright ignorance regarding RH5 wheels. I've taken wheels and tires to so called tire shops and they didn't know the difference between RH5's and split ring wheels. "If it is a 20 inch wheel it is automatically a widow maker" (RH5) My 72 sees very little use, less than 1,000 miles a year, the cost of 7 new 22.5 wheels ($329 each) plus 7 tires (~$300 each) =$6,000 plus is cost prohibitive. I always wondered if anyone made adapters that allowed mounting the large diameter bolt circle steel wheels to be bolted on our older trucks. These semi wheels are commonly available locally for $25-$50. Anyone know of a source for such an adapter?

You could buy a tire hammer and a couple of levers and do it yourself.Way cheaper than investing in tubeless wheels and tires. It's just brute force not rocket science.
Many years ago I didn't have 2 nickles to rub together and couldn't afford to have somebody changing my tires. At that time I was working at the IH truck shop as a general mechanic and that meant changing tires too. The shop had had a fire and lost many tools in it. So one payday when the Mac Tool man came around, I bought a couple of tire levers and a 20 lb. slide hammer which I still have to this day. They work on split rims, assorted tractor tires and others. I have never encountered an RH-5, just Budds, other split rim wheels, Chevrolet 3-piece wheels and various tubeless tires. Later, when I worked for a hay company the boss made the drivers fix their own flats. I suppose that made us drivers more careful around the nail infested barnyards. Those trucks all had 20-inch Budd wheels.
