ULIP inner tube marked 20 × 4.0 and 3.50-16

The wide ULIP inner tube has a straight Schrader valve and a dual dimension marking of 20 × 4.0 / 3.50-16. It is intended for the matching tire and rim of a wide wheel assembly.

Features and fitment

  • Model: ENGWE L20 Boost.
  • ULIP 20 × 4.0 / 3.50-16; straight Schrader valve.

Approximate dimensions

  • Outer tube diameter: 565 mm.
  • Inner tube diameter: 408 mm.
  • Tube width: 80.9 mm.
  • Valve length: 30 mm.

The straight valve is approximately 30 mm long. When choosing, compare the full dimension marking on the old inner tube and tire, and check the access to the valve after installing the wheel.

Replacement without pinching the inner tube

  • Before replacing, find the cause of the puncture in the tire or on the rim. A foreign object, sharp edge, or damaged rim tape can immediately damage the new inner tube as well.
  • Slightly inflate the inner tube, align the valve with the hole, and distribute it evenly in the tire. When installing the tire bead, do not pinch the tube with mounting tools.
  • Inflate to the pressure allowed for the wheel assembly. Check the position of the valve and the seal; do not use the valve cap to stop a leak.
