Has anyone else had problems with cracking of this wheel? We lost an entire segment of the rim, spoke to spoke, on one wheel yesterday and had to splint cracks in another. This appears to be happening when going over bump. Cracks seem to form on outside of facing side of wheel first and then propagate through wheel. Since the robot never comes down off of the bump completely square to the floor, the outside of one rim takes more of the impact. This is what we think is causing wheel to crack. At least that is what appears to be happening.
