Does the tread just come off such small wheels, or is there another problem? I was thinking of just using a colson if what you're saying is the case.



I recall seeing old threads about a team machining the paint off the CIM to make it shiny, but I want to avoid machining more COTS components than absolutely necessary. That being said, replacing the front plate of the CIM would be an elegant solution.

A colson would work better as the bond to the polyolefin core is very strong, but it would still wear out faster than you'd think.

Replacing the ends of motors has been on my "i'd like to do this..." list, but I never have as I'd likely lose the rules argument, you are getting a weight/performance advantage when you integrate the motor into the structure like that. And I read "modified to facilitate mounting" as "mess with it some if need be, but don't replace it".

I had a concept once that would replace the dead axle of a window motor with a powered shaft through to get an on-axis steering motor, but never made it past that as I'm pretty sure I'd lose the legality argument.
