Does anyone know what is the original equipment tire size for a '68 f250 and where did you get your information? Getting conflicting info from all over the place. Just need 4 maypops to get this vehicle from a field to my home. This truck was left in a field in w Texas, probably last driven in the 80's. No date on the license plates. Also (icing on the cake) no rusted through spots anywhere on this truck. Some light surface rust, but that's all. wow. Tires that aren't flat probably won't hold air, so need something that will get it home.
