Chaoyang inner tube for 4.0 to 4.9 widths

The Chaoyang 20 × 4.0/4.9 is an inner tube for compatible wide 20-inch tires. The black rubber design features a straight valve approximately 32 mm long.

Features and Compatibility

  • Model: ENGWE L20.
  • Chaoyang 20 × 4.0/4.9; straight valve approx. 32 mm.

Approximate Dimensions

  • Outer diameter of the inner tube: 550 mm.
  • Inner diameter of the inner tube: 400 mm.
  • Width of the inner tube: 60 mm.
  • Straight valve length: 32 mm.

The 4.0/4.9 range indicates the tire widths for which it is intended. Please verify the valve type and height; once installed, it must be accessible for your pump and straight relative to the rim opening.

Replacing Without Pinching the Tube

  • Before replacing, find the cause of the puncture in the tire or on the rim. A foreign object, sharp edge, or damaged rim strip can immediately damage the new inner tube.
  • Inflate the tube slightly, align the valve with the opening, and distribute it evenly within the tire. Be careful not to pinch it with tire levers during installation.
  • Inflate to the pressure allowed for your wheel assembly. Check the valve position and sealing; do not use the valve cap to stop leaks.
