I bought a 1955 Ford 850, which came with pie weights on the rear tires. I was driving it and one of the rear wheels fell off. Whomever installed them only had 4 lugs on the inside. Anyway, there were spacers (lug extensions) inside the tire, between the wheel lugs and the tire rim. We don't want to keep the weights on the tractor, and the extensions were damaged, so we were going to just put the tire on using just the new lugs, but it seem that there is not enough clearance, the inside of the tire would rub on the fender.... soooo looking at pictures we can find, we think that the tires are probably wider and shorter than the original design. I haven't been able to find where I can buy new extensions, since the old ones are damaged. Any suggestions? Thanks.
