Look on the wheel for a Wheel Code next to the valve stem hole. It should correspond to one of the codes in the left column here...

This will tell you what the wheels were originally for. This list is not all inclusive by the way.
Are they ralleys or steel wheels? 63-66 Corvette steel wheels are 15x5 1/2 (as were the optional 57-62 wheels). 67 ralleys were the only Corvette wheels ever used in the 15x6 size. 65-66 OEM wheels are "J", and the service replacement ones are "JK"s, I think.
Does anyone have a comprehensive list for regular steel wheels?
My 65 had 15x6 rims with the nubs by the valve stem when I got it...they have a code of FL
I've tried to identify these here and on google and have come up empty.
Those might be the old "8080" Service wheels. Corvette steel wheels didn't have any code stamping adjacent to the valve stem until the 1967 "B", "DC", and "DG" rally wheels. The "JJ" and "JK" stampings referenced above are the SAE rim cross-section design codes, and are stamped in the rim area covered by the tire; '66 rim stampings shown in the photo below.
