Installation Tips

  1. Confirm your tire size before purchasing — 20×3" and 26×3" are not interchangeable.
  2. Before fitting the new tube, inspect the inside of the tire for sharp objects or embedded debris.
  3. Add a small amount of air to the tube before installation to give it shape and prevent pinch flats.
  4. Feed the valve through the rim hole at a 90-degree angle and hand-tighten the valve cap.
  5. Seat the tire fully on the rim before inflating to recommended pressure, ensuring the tube is not pinched.
