Complete 20×4.0 replacement set for compatible fat-tire e-bikes and bicycles. The kit combines a directional-tread tire, inner tube and protective tire liner, plus the small installation accessories shown in the product photos.
Verify fit before ordering
- Confirm the existing tire sidewall is marked 20×4.0 and that the rim is designed for this size.
- Check frame, fork, fender and brake clearance for the mounted tire.
- Compare the tube valve style and valve length with your rim.
- Confirm the tire’s directional arrow during installation.
About the tire liner
The liner adds a protective layer between the tire and inner tube and may help reduce punctures from some small sharp objects. It does not make the assembly puncture-proof, does not support riding on a deflated tube and does not guarantee protection from blowouts or rim damage. Stop riding promptly if pressure is lost.

Installation notes
Inspect the rim tape and rim before installation, remove any debris, center the liner without folds, lightly inflate the tube before seating it and ensure the tube is not pinched under the bead. Inflate gradually to the pressure range marked on the tire and check that the bead is seated evenly. Professional installation is recommended if you are unsure.
