WOW, tons of info and ideas. Thank you, huge learning experience. Now I know how to search as google can be stupid, showing me photos of sewing machines when I specify tires. Guess sewing machine have "tires" or wheels. So I looked closer at all the tires, one member was right, there is one different tire on there, all 4 have the continuous flange with a split locking ring that goes between rim and flange. The one rim looks like the Kelsey-Hayes WK-4, the other 3 look like the Type AR rim. If these rims are good, I will go back and look for matching rim(s). Unsure what is out there but may be a good day to search the yard for more stuff. If the rims not good, then I guess I'll have to invest in solid rims if I can find them. I do have a set of steel rims but very close to the steering arm and wider, got those mainly to move truck around while working on it cause the split rims were making me nervous airing up at every flat to move, I only air it up to maybe 15-20 lbs. just to get it rolling. Here are some photos of the rims. If they are usable, which ones are the best type and what do I look for in cleaning up? Only thing I see rusted is the locking ring, rest appear good.
