I recently purchased an IH 606 with power adjust wheels. They are loaded with calcium and as you can guess are pretty much shot. I got a set of discs and rims and was curious as to the position to mount them. Disc with dome in or out and then what position for the 6 loop rim? I’m pretty sure I want to keep the valve stem out for easier access but that still leaves a couple options. Reusing the tires with new tubes. Thanks.
