If your Razor Dash needs new rubber, then our 12-1/2"x2-1/4" Tire & Inner Tube Set for the Razor Dash is a superb deal. This is the same 12" tire that Razor uses on a variety of their models, so you know it has stood the test. We bundled this great little electric scooter tire with an inner tube that sports an easy-to-access straight Schrader valve stem.
