Checks to carry out before installing an inner tube:
- Check the condition of your tyre and replace it if necessary.
- Make sure no objects are lodged in the tyre.
- Check the condition of your tyre rim strip. A rim strip that is even slightly bent can cause punctures.
- Check that your rim does not have any other issues that could damage your inner tube.

Mounting the inner tube:
- Watch our video before you start.
- Pre-inflate the inner tube slightly to avoid pinching.
- Insert the valve, making sure you are using the correct valve for your rim.
- Put the inner tube entirely inside the tyre so that it fits inside the rim.
- Take care not to pinch the inner tube when fitting.

Mounting the tyre:
- Start mounting the tyre at the valve.
- 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 the tyre:
- Inflate your tyre carefully, to the pressure recommended by the manufacturer (visible on the tyre sidewall in psi or bars, 1 bar = 14.51 psi).
- Regularly check that your tyre is in the correct position as you inflate it.

Tip from the pros: To avoid punctures from pinching and for the best tyre performance, we recommend that you check your tyres and inflate them to the suggested pressure before every ride.
