I have a cousin that won't drive anything that is not a Ford. When my cousin progressed into modern pickups, '57-66 he always ordered the F100 with 16" wheels, 650 x 16" tube type tires, some little quirk of his.. When he bought a new '73 F100 he had to relent, settling for 15" tubeless tires.
My father who was a ceramic tile contractor had so much trouble with the light weight wheels the '30 model pickups had, I can remember several instances where wheels cracked and broke at the bead, taking the rear fender with it, dad insisted on either having the artillery type wheel or 16" spit rims with 650 x 16 6 ply tires.
As a general rule the 15" & 16" Ford wheels of the mid '60's and later are a HD type wheel, usually stamped with DOT spec numbers, the wheel size 15 x 6 and 2,200 lb. or heavier rating..
