I have a supply of original wheels for my 53 half ton that I'm working on. All of them are 16 inch wheels with clips for the hubcaps. If I measure the width, outside to outside, most of them measure 5-1/8, 5-3/16, and 5-1/4. I consider these to be OK to mix on the truck. But some measure 6 inch diameter. Can you guys tell me which size is actually correct for my truck? Also, I have 4 wheels on the truck now that are 16 inch, 6 lug, but have had clips added to them. What would they have come on originally. I just want to educate myself a little bit on these. It seems that there are a lot of very similar wheels that are not quite identical. P. S. none of there are split rims. All are standard one piece wheels.
