Sorry Ed but you confused me. I know I have 20” wheels. Let me add this the tires are 32-6 10 ply, which according to the 37 spec book they should be mounted to a 6” rim. My question is can I run the 8.25-20 on these rims on my 37 1.5 ton. One other question and it may sound dumb. How do you measure wheel width on these old rims? I see conflicting info on the net. Today we measure inside the rim where the bead sits, still the same? Trying to upload a picture of rim but not working on my phone... measurement from outside to outside is like 5 3/8”
