I have a ford 1500 that is in good shape excluding the rear rims. The tires are 13.6x16 and have a good amount of tread on them whoever they have been loaded with calium and the rims are quite rotted on the inside on the hub. I have been looking for used rims but haven't had much success Would it be worth trying to grind away the rotted areas and wield a rectangular piece of metal wrapping the interior of the rim and grinding smoothout the rough spots. The tires also have tubes.
