There were no wide wheels offered by GM in 15". The only wider wheel option was the 16.5 x 8.25s for mounting the 10.00 x 16.5 flotation tire option. Not sure those were available on C/10s, but they were on K/5 & K/10, so 6-lug. You either have aftermarket, like Kelsey Hayes, 15 x 8s or factory option from later in the '70s. You can buy this size wheel new from Wheel Vintiques now. They also offer them in 7". As Uncle mentioned, no 7" wheels were offered from factory. Wheel width is measured between the inner bead surfaces with no tire mounted.
