In fact, its width can be extended to 5.0"+, in order to ensure quality, we conservatively used in the 3.5/4.0 range to ensure its life and air tightness, and reduce the frequency of wear and replacement.
  • HEAVY DUTY - Air Tightness: Using high elasticity and high quality butyl rubber and EPDM rubber, the thickness is increased by 40%, and the air tightness of the inner tube is increased by 200% than that of the ordinary butyl inner tube; After inflation, the tire can maintain a higher air pressure for 6-9 months, greatly reducing the inflation frequency. Good air tightness helps keep tire pressure stable, thus improving driving safety.
  • HEAVY DUTY- Ultra Durable: Our heavy duty inner tubes have higher puncture resistance than ordinary inner tubes, and the thicker body can withstand more friction and wear, thus extending the service life of the tube, reducing replacement frequency and maintenance costs. And in long-term use.
  • Excellent shock absorption ability: The heavy, strong, highly durable butyl rubber made from these inner tubes is a perfect shock absorber to reduce vibration and eliminate the shock caused by bumps and rough surfaces on the road or pavement. Heavy Duty butyl rubber for maximum ride comfort - upgrade your ride experience.
  • Installation: 20''x3.5''/4.0" bicycle heavy duty replacement inner tube for easy installation and removal. Check the valve position to ensure that the installation direction is correct.

  • Tip: Before installing the inner tube, please put the inner tube into the water for inspection, if there are bubbles, it means that it has been damaged, you can contact us.
