if the wheels were metal and the roadway was also metal, but arranged into parallel small roadways, then we could avoid using rubber and not have the problem of rubber particulates.
Seems like in that case, you could just use cogwheels and racks, and avoid the complexity of legs.
like, trains?
Yes, specifically cog railways.
Metal particles are more reactive and toxic than rubber particles.
