Some larger wheels were available two to three years ago...in the "George size" not sure, but they were available in 17's & 18's which I got. I think it was a matter of just using a larger hoop 19 & 20 and those were available....the CNC program, I assume could easily change that dimension.
Below are the wheels I purchased directly from Coddington in 2007. It took me about six months to get Coddington to get an agreement from Marino to allow them to make the wheels in the sizes I wanted. Marino would not make them in the size I wanted...so he allowed Coddington to make them for me.
I've heard that Coddington (Boyd Jr) does not make Mario's wheels anymore??? Can anyone confirm that? I was thinking that Boyd Sr. died and the wheels business was sold to Wheel Pro's it made the exclusive contract for these wheels for Marino ONLY invalid?
