PURPOSE: To obtain a tire with slip stoppers without public nuisance by forming a tire in such a way that holes are opened in the tire, slip stoppers are fitted into the holes, so that they can freely project and retreat by electromagnets.

CONSTITUTION: Holes 2 are opened in a tire 1 and pipes 3 are fitted into the holes, and slip stoppers 4 with magnets 6 are fitted movable vertically. And a magnet 5 is fitted to the tire 1, and the slip stoppers 4 are allowed to project and retreat by electrifying magnets 5 and 6 and changing magnetic polarity appropriately. Thus, a tire with slip stoppers without public nuisance can be obtained.
