Here's a photo of the damage. (Hopefully the quality is good enough! I had to take everything from my phone yesterday, sorry.) That's tape over some of the more noticeable gashes. No pops yet though.

We've been using 6" treaded wheels and I noticed little pieces of the blue fabric sticking from each contacting edge of the wheel. I'm hoping that we try the smooth gray wheels from Andymark this week, and that causes less damage. Plus right now, the CIMs are just going full power as we haven't done the electrical/programming yet, so hopefully at a lower speed it will be better too.
