> It would still wear rubber away just like tires do.
It’s been a hot minute since I learnt rolling friction in high school physics but (iirc) a very interesting and unintuitive aspect of it is that there’s always an opposing/slowing force on a (rubber) wheel. Only a slippping wheel will not experience a slowdown. Static friction is different from rolling friction, and (I think) can offer zero wear in ideal conditions - but rolling wear is always non-zero.
