pic: Wheel progression

[Anupam Goli]

I'll get a picture of our drivetrain wheels, but we are seeing similar wear on the tire version of the diamond tread on both our practice and competition bot. The grip these suckers had when they weren't worn (and they still have decent grip) was great, but we're going to drive the practice bot a little bit more aggressively than before to see if the wear on the wheel is affecting its performance. It'll be a pain to switch the treads on the wheels, but if we find we're getting significantly better performance using the blue nitrile or SBR tread we used last year, we're ready to do that switch.
