I shared the info. with the other driver. I think they are very unique, and in my years, I have yet to see anything like them. I don't think I could ever convince him to try out a different type of wheel though, or even something similar. We were
very successful with our wheels this year too. We used to use four of the wheel chair wheels. We upgraded to large (mini swamper) Skyway wheels this year. They were awesome directly from Skyway, but our wheelman (evulish) made them even better.
Maybe I can get him to post a picture of the wheels after he perfected them.
