Impossible to guess. Looking at what appears to be an absence of calculated profiling of the timber roller, I would say that the degrading possibilities have not been addressed. The motor shaft, and the roller rotate at the same speed. The speed of the roller differs, depending on exactly where it contacts the roller. There obviously would be some discrepancy.
What would degrade more, the rubber tyre or the wooden roller? The tyre would just wear out but the wooden roller would head towards conforming to a more suitable profile - if it was soft enough. Would that happen before the tyre wore out?
