Hey, how yall doin?

I need help identifying the type of these older GM rims to find out their dimensions like offset and bolt circle diameter.





Only thing I found was a "7-92" stamped on the backside of the rim. They came with my '91 Firebird but I never used them, I prefer the original Pontiac rims.

Those look more like American Racing rims than GM rims.

 

except for color they look like American Racing wheels I had on my P/U many years ago . good luck ...

 

Use a tape measure?

 

If you break the tire off the rim there should be identifying stamps or codes inside.

There may also be codes on the back side - clean the wheel very well, they are sometimes hard to read.

 

Those are American racing "wagon wheels" that someone has painted black. Or if they're newer then they're most likely made by "US wheel"

Thanks a bunch guys!!!

I am always overwhelmed by the support this board offers even with such 'stupid' and 'simple' questions.

On the backside it also reads "GM" next to the "7-92" so I thought it must be GM rims. But thanks to your information I am now confident that those are American Racing wagon wheels... They have had a chrome/steel finish before the previous owner painted them black. In case I want to sell them it is important to know the type.

Using a tape measure is fine, but not for german state inspection. They like to be presented with the original parameters as specified by the manufacturer. Maybe I can also find something on the inside by breaking the tire off, thanks for the hint!

the GM probably signifies that it's a GM bolt pattern. If you know the size (like, 15x7, etc) you might be able to just look up a "new" set and get the paramenters off whoever is selling the new set.


glad to help!
