ULIP inner tube with 20 × 4.0 and 3.50-16 markings

The wide ULIP inner tube features a straight Schrader valve and double sizing: 20 × 4.0 / 3.50-16. It is designed for the corresponding tire and rim of wide wheel assemblies.

Features and fitment

  • Model: ENGWE L20.
  • 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. Before selecting, compare the full sizing designation on the old tube and tire and check valve access after installing the wheel.

Replacement without pinching the tube

  • Before replacing, check the tire or rim for the cause of the puncture. Debris, a sharp edge, or a damaged rim tape can immediately damage the new inner tube as well.
  • Inflate the inner tube slightly, align the valve with the opening, and distribute it evenly inside the tire. When seating the bead, do not pinch the tube with tire levers.
  • Inflate to the pressure permitted for the wheel assembly. Check the valve position and for any leaks; do not use the valve cap to stop a leak.
