These are all good ideas guys, thank you very much.

I thought of another one while talking to a teammate: a thick car timing belt as a rigid backing to weather stripping. The timing belt would increase the radius, while the weather stripping would increase the coefficient of friction. A long-enough timing belt would be wrappable around the wheel multiple times, and any little bumps would be smoothed over by the weather stripping layer. Any thoughts?
