Check the information indicated on the sidewall of the tyre (diameter and width). For example, 20 x 2.10 means that the tyre is 20 inches in diameter and 2.10 inches wide. On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 50-406 means a tyre that is 50mm wide and has an inner diameter of 406mm (approx. 20 x 2.00).

Remove the used inner tube using B'Twin tyre levers (ref 8047839).

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.

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.

Start by mounting the tyre onto the wheel on the opposite side to the valve. Finish mounting the tyre at the valve to avoid pinching the inner tube. Never mount your tyre with a screwdriver or a tyre lever, as you risk pinching and puncturing the inner tube.

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.

To prevent any puncture from pinching and to achieve the best performance, we recommend checking and, if necessary, pumping up your front tyre before each ride.

You'll need a tyre lever (reference 8047839) to change your inner tube. If you want to repair a punctured inner tube, you can use repair patches (reference 8563156) or self-adhesive patches (reference 8562489)

Carry your inner tubes in a container to protect them from getting punctured (B'Twin carry case, original packaging, etc.).

To guarantee optimal quality, 100% of our inner tubes are inflated for a period of 8 hours.
