My '48 F3 has 14" rear drums (12" fronts). If you have 14" drums, the 16" wheels, will not fit.

I put 12.50 x 16.5's on the rear of my truck but, I had to machine at least 1/8" off the enter rib to make them fit. If I had known, I would have to do that, I would have looked into 17's but, I had already bought the tires and wheels.

For loaded trucks, what has been said about insuring that the pilot hole fitting the hub is important. It takes the weight and insures that the wheel runs true.
