How do I keep my mountain bike tires from going flat?
Use Talcum Powder. A little bit of talcum powder goes a long way. Liberally dusting a new inner tube with talcum powder before installation reduces chafing on the tube’s rubber surface. This keeps the tire and tube from sticking to each other and lessens friction that can possibly wear a hole in the tube.
