Wht do you think mountain bikes have rubber tires? Or one of these? https://en.wikipedia.org/wiki/All-terrain_vehicle https://en.wikipedia.org/wiki/All-terrain_vehicle Or a dune buggy? Pretty clearly the worry about the road surface is not the only cause of using tires. Also, if you don't care for either preserving the surface or comfort (use something else for comfort) then... use metal wheels. Or ceramic wheels, or tracks or something.
