Fits 20x4.0 fat tires: Designed for 20 x 4.0 fat-tire e-bikes and bicycles. Includes one protective insert for one wheel. Outer tire and inner tube are not included.
Helps reduce punctures: Creates a protective layer between the outer tire and inner tube to help reduce punctures caused by thorns, goatheads and small sharp debris.
Inner tube protection: The contoured design covers the tread area and extends toward the sides, helping protect the tube from direct impacts and reduce pinch flats around the rim.
Added cushioning and reusable design: Helps absorb bumps and vibrations for a more comfortable ride. The insert can be removed and reused during tire or tube replacement if it remains undamaged.
Installation guidance: Soak the insert in warm water for several minutes to improve flexibility. Center it between the tire and tube, then inflate gradually while checking for pinching.
