We had received two old wheels and two new wheels with our first order, and had unwittingly put all four on the robot without replacing the old rollers with the new ones that were included. The old rollers quickly wore out; the roller shaft was not rigidly held in place and allowed the rollers to bind up on the wheel body.
The new rollers seem to last really well. We did notice that they become a bit harder to turn by hand after a lot of use, but I'm not sure that it's enough to affect the driving. We may do an experiment at some point to see how a well worn wheel performs next to a brand new one.

A bit off topic, but can you elaborate on the failure mode? I think that we may be using more vexpro parts in the future, and I'm really digging all of the inexpensive plastic components they make.
