Here is a 16" wheel I have had laying around and no longer need. It has 8 bolt mounting on 6 1/2 inch bolt centers, 6 1/2 inch bead width, and about 4 1/4 inch backspacing.
It came with a 1995 Chevy K 2500 3/4 ton pickup that I had years ago. The tire is like new tread-wise, but does have a cut all the way through the sidewall. This pattern fits many Ford, GMC, Chevrolet, and Dodge 3/4 and 1 ton pick-up trucks.
