I can't seem to find the model anywhere. They are 8.5x18 up front and 10x18 in the back. I can't find any offset markings anywhere either. Thanks in advance.

 

I haven't seen these before. Maybe it's the pictures, but things look out of proportion to me.

 

I was told they were custom ordered to spec. by the P.O.

 

Aren't they the old 540 series? Man I haven't seen that old school HRE emblem in a while.

 

check the back of the rim's, there should be your offset numbers imprinted
also there should be serial numbers for the rim. You can use those numbers and check with HRE directly and they can tell you the offset and model style.

 

Not sure of the model but they are older for sure. Good looking wheels

 

Wow! You're going old school on me. Those were referred to as the 340 when they were last in production. They are a forged center.

If you want, give me a ring and I will be more than happy to help you get all the info you need.
