This allows you to choose with confidence based on the markings printed on your tire sidewall.

How to Choose the Right 20” Inner Tube

To ensure a perfect fit, always check:

  • The tire size in inches (e.g. 20x1.75, 20x2.125)
  • The ETRTO size, printed on the tire sidewall (e.g. 47-406, 54-406)
  • The valve type: Presta (FV), Schrader (AV), or Dunlop (DV)

An inner tube always covers a range of tire widths. For example, a 20x1.75–2.125 inner tube is compatible with multiple tire sizes between 47-406 and 57-406.
