<p>Protrax was founded by a couple of power sports enthusiasts who ride on what they sell. If it's not good enough for us, it's not good enough for you. Don't settle for a cheaply made tube and risk having a flat tire.</p><p><strong>The reason our tubes exceed expectations and blow any 4mm tube out of the water is:</strong> 1. Our tubes are made from a mix of natural rubber and butyl rubber, known for durability.<br /> 2. Our tubes are designed for motocross and to endure trail rides and challenging roads.<br /> 3. Our tubes are thick enough to last without adding excess weight to your bike. <br /> 4. We manufactured the tubes by our standards, and we ride with them ourselves.<br /> <strong>Try Protrax today and say goodbye to carrying flat tire kits and spares. Add to cart risk-free.<strong><br /></strong></strong></p><p><strong>Pro Tip: </strong></p><p>If you change the tube yourself remember: <br /> Install with baby powder when the tube is partially inflated to avoid twists, kinks, and wrinkles.<br /> Use tire spoons. <br /> Inflate and deflate partially multiple times before reaching full factory recommended pressure. <br /> make sure when you are re-seating the tire after the new tube is inside that you fully seat one side<br /> of the tire on the rim before trying to get the last side on.</p>
