What size are these hubcaps?
 

Got alot of spare parts with my C10 when I bought it, now I want to recoup some money by selling off some. I have heard these caps came in 16" and 15" but I don't know what these are and I don't have steel wheels to try them on.
Anyone know how to tell?
Thanks

I wouldn't know what they are but I'd imagine it would help the others if you posted the diameter. I'm sure someone on here will chime in.

Re: What size are these hubcaps?
 

If they are 12" diameter they are 3/4 ton caps (8 lug steelies)
If they are 10.5" diameter they are 1/2 ton caps (5 or 6 lug steelies)

They are also 76-up caps.

Those are 10.5" caps. The 3/4 ton had 6 black spots on the outer edges in these years.

There are 15 and 16 inch wheels...as well as other diameters. What matters with hubcaps is the lug pattern, not rim diameter (except with wheelcovers). The centers of this type of wheel are standardized between the smaller size for 5 & 6 lug and the larger for 8-lug. As Eric said, these 76-91 GMC caps are easy to ID due to the 8-lug caps have 6 spokes and the 5/6-lug having 5.
