How to Choose the Right 12-Inch Inner Tube

For an effective replacement or repair, several factors should be considered:

  • the exact tyre size (width and diameter)
  • the valve type, depending on the rim and intended use
  • the type of vehicle: everyday use, leisure, children’s use, light load
  • the frequency of use, which may justify a more robust inner tube

A correctly sized inner tube helps prevent pinch flats, premature pressure loss and extends the lifespan of the tyre.
