Then again, the wheels were redesigned to handle greater side loads without breaking the spokes, and this might just be how they react now.

Thats exactly what happened a simple impact, this happened on our 2009 robot. We had 6 similar wheels like this one on the robot. This was caused by going forward then reversing fairly quickly. The front four wheels then came off the ground then quickly back down crushing this wheel.
