I looked last night the two wheels I just refinished.
YOU MIGHT BE LOOKING AT THE WRONG CODES. Those look like later wheel codes next to the valve stem opening. The ones I have in that location are "HP" which is a Honeycomb wheel code.
The codes for your wheels may be stamped on the inside of the wheel on the backside of the front face. It is after the size of the wheel in inches. Mine say "15 x 7 JJ" which is a proper code for 15 x 7 rims with a 4.75 inch bolt pattern.
