Check the information indicated on the sidewall of the tyre (diameter and width). For example, 700 x 35 means your tyre is 700mm in diameter and 35mm wide. On the sidewall, you will also find the dimensions in mm in international ETRTO measurements. For example: 35-622 means your tyre is 35mm wide with an inner diameter of 700mm (so 700 x 35)
Remove the old inner tube using B'Twin tyre levers.
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 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.
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.
Carry your inner tubes in a container to protect them from getting punctured (tool drum, original packagingâ€¦).
To guarantee optimal quality, 100% of our inner tubes are inflated for a period of 8 hours.
