Like always I can be proved wrong.
I cannot find anything online that says GM used 16.5" wheels stock from factory.
BUT
I did talk to my father-in-law, who has worked at a dealership or for himself sence his teens and is 2nd generation of this, worked at a GM dealer in the late 70's and early 80's and told me that "yes gm 3/4 and 1 ton trucks came from the factory with 16'5 wheels". It was so a person could not put cheap car tires on a "heaiver" truck and risk blowing them up at heavier towing.
Also here is another note. In 4x4's you can put a Ford 16.5 rim on a GM but not put a GM on a Ford. There for if Ford was the "only" one with 16.5's then this would not be so. It has to do with the inner dimention of the axle hub hole. GM's were just a tad smaller than Fords.
I am still looking around the net to find hard copy info but what I have stated has been from general knowledge and looking for parts at junk yards and/or not knowing the answer and asking anyone and everyone I knew.
I can be proven wrong at any time though!!! I am NO expert nor claim to be!!!!
