AndyMark didn't invest in molding and manufacturing
these wheels just because they thought they could sell a few.
I can almost guarantee these are the KOP wheels which would lend credence to the smaller bot ideas. Also the FIRST Choice hold back suggests that FIRST is changing things up a bit and want teams to be able to get extra chassis parts and wheels.
BTW I have worked at AndyMark in the past but my current job makes that impossible and I have zero inside information on this.
