Mr Tuffy prevents puncture flats.
When placed between tyre and tube, it provides a protective layer between road hazards and the inner tube. Thorns or glass that may penetrate the tyre are blocked from the inner tube. Proven tough for over three decades Mr Tuffy has been the world's leading flat-tyre preventive with millions upon millions of satisfied cyclists.
