New Tread from AndyMark - Pebbletop Tread

We're using 4x 4" colsons for FTC and have no problem driving up to mid. More than high enough for our climbing mechanism to engage the pull up bar for our 80pt hang. It has nothing to do with your tread pattern or which wheel. Teams around us have tried every combination of wheel and it really has nothing to do with engaging your wheel on the churros.

If the geometry of your drive base is done correctly and your COG is far enough forward (something we struggle with every time we add or remove a mechanism), I'm confident a much less grippy wheel like roughtop on the plastic pyramid would work just as well.


That being said, this is a cool alternative for FRC teams who use treaded wheels. The pattern is much closer to the VexPro W-Cut wheels which is probably the best COTS wheel for traction in the forward/backward direction due to the nature of the horizontal cuts.
