The impression I got is that having this tread available makes it so teams can use plaction/performance wheels in addition to the other 4" wheels in AndyMark’s line of products for FTC. This year, FTC has legalized any wheel 4" in diameter or under (and it’s well worth it, too; our FTC teams are running the 4" HiGrip wheels right now, which have a much greater coefficient of friction against FTC tile than normal FTC wheels). We tested a VexPro wheel with both wedgetop and roughtop tread, and that had an even greater coefficient of friction than the HiGrip wheels.
But isn’t the new kitbot that is coming out for 2014 being made so the middle wheel is a direct drive 6in wheel? I remember reading that a while back so it would make more sense that they are stressing it for FTC purposes over releasing a kitbot that wouldn’t be legal.
