How to choose an inner tube:
To maintain your bike properly, it's important to know the exact dimensions of your tyres.This information appears on the tyre sidewall (diameter and width).
For example, 12 x 1.60 means that the tyre is 12 inches in diameter and 1.60 inches wide.
On the sidewall of the tyre, you will also find the dimensions in mm in the international unit ETRTO.
For example, 40-203 means that the tyre is 40 mm wide and has an internal diameter of 203 mm (i.e. 12 x 1.60).
To remove your inner tube, the tools you'll need are:
Remove the old inner tube using a tyre lever.
Checks to carry out before installing an inner tube:
Always carry out a full inspection before installation:every detail counts to avoid a puncture.
How to change an inner tube:

Fitting a tyre:

Finish mounting the tyre opposite the valve to avoid pinching the inner tube.
Never mount your tyre with a tool or a tyre lever, as you risk pinching and puncturing the inner tube.
Inflating a tyre:
