Dynaplug 5-pack of bullet nose brass Tip Repair Plugs are very rounded and chosen by riders concerned with a more pointed tip. When needed, just remove whatever caused the puncture, firmly push the tool’s novel insertion tube straight (without twisting) into the hole and extract the tool depositing the repair plug in the tire. Used in the tread, sidewalls, and along the rim. Add as many plugs as needed, folding each tail against the tire as you insert plugs.
