According to the history, the CM1 wheels were made by the parent company of Beta Crafts. So, is it possible that these wheels are still being made? I don't know, but it might be worth sending an email to the company and asking. Those would have been the same kind my car had the one time I got to do pinewood derby as a kid, so I'm curious about this as well.

Yep, that is what the article on Maximum Velocity said.
I have not been able to find them for sale by any company. I was able to get some from a member on another forum. My guess would be that when CMI (now Beta Crafts) lost the BSA contract they got rid of the molds. I can't say for sure but that would be my guess.
