How to Choose the Right 12-Inch Inner Tube

For an efficient replacement or repair, consider the following criteria:

• the exact tire size (diameter and width)
• the valve type, depending on your rim and usage
• the type of use: everyday riding, leisure, kids’ bikes, light loads
• the frequency of use, which may influence the choice of a more reinforced inner tube

A properly sized inner tube helps prevent pinch flats, premature air loss, and extends the overall lifespan of the tire.
