Personally I like the look of the 17.5s on my bus, they fill the wheel well, nicely. I looked at your pics, are those the tires in the back of the truck? Good lookin tires, try them on your truck and see what you think, then imagine BIGGER (19.5s) And ask yourself, "what am I going for, with this truck?" restore, semi-restore, modded. You may decide the 17.5s are what you want.
The truck is a one ton 5.14 rear so figure the 19.5s to help with highway speeds as to use plan to use it as a local parts runner and maybe a back up tow vehicle to my 79 K35.
