Rims are measured where the bead of the tire sits so if you're measuring from outside edge to outside edge and get 16.5”, it’s most likely a 15” rim.
Here is a photo of a 15” rim and it measures 16.5” outside edge to outside edge. Please note the picture make it look like I didn't have the ruler centered on the rim, but it was and it’s just an illusion.

WarEagle1 - For a whole bunch of details on your 1965 C10, check out this original GM 1965 Chevy Truck data file. Be aware that the beginning of the file lists K10 & K20 info (applies to the 4X4 trucks) and you will need to scroll down until you find the C10 (2 wheel drive) series info to find such details. Happy reading
