Not sure if this should be posted here but my wheel code does not match any of the RPO codes. The code I have is JJ could anyone tell me what it means?

thanks

 

It might be a part identification code. I wouldn't think it would have much to do with the RPO code although there may be a list somewhere (internal GM) that states this RPO code gets these rims with this part code.

With multi piece steel rims (your pictures are a bit small in your gallery so I can't really tell what they are),You have 2 different pieces that make up the rim, the center section, then the hoop. It is possible that the JJ is the code for the hoop or centersection, depending on where the mark is located.

Also, this could be a date code or an inspector identification. Are there any other numbers on the rim?

 

Looks like you've got the Rally Rims...

The JJ code could be for different center caps... I.E: Bowtie, or 4x4, or GMC
