Maybe Stu 'Truckdog' McMillan will chime in. You haven't told us the year, but since the F3 was built from 1948-1952, that;s the range. I had a '51 F3 and I used typical steel wheels from '90s F250 with tubeless radials. These were of course 16". There was a change, perhaps in mid 1951 or 1952, where larger rear drums were employed and the 16" wheels would not fit on the rear. If you have the older drums your best bet would be 'innie' 16" wheels from a F250. These phased out in the mid 60s. Innie wheels have the hubcap nubs facing inwards. In my case I ran 255 85r 16s, which are narrow and about 33" diameter, for the look and gearing of a 17" tire. Also there are specialty outfits like 'Stockton Wheel' that will put your existing wheel face into a tubless hoop. If this leads to .5 tubeless rims, far better to go with 19.5s instead of 17.5s, as the available tire family are all low profile, and they don't look right and your effective gearing will be lower.
