Check the sidewall for tire information (diameter and width). For example, 27.5 x 1.90 means a tire with a 27.5” diameter that is 1.90” wide.
The dimensions in mm (ETRTO international unit) are also on the tire sidewall.
For example 50-584 means the tire is 50 mm wide with an inner diameter of 584 mm (or 27.5 x 1.90).

How to choose your inner tube

Remove the old inner tube using Btwin tire levers.

Removing an inner tube

Check the condition of your tire and replace it if necessary. 
Make sure no objects are lodged in the tire.
Check the condition of your tire rim strip.
A rim strip that’s even slightly bent can cause punctures.
Check that your rim doesn’t have any other issues that could damage your inner tube.

Checks to carry out before installing an inner tube

Watch our video before you start.
Pre-inflate the inner tube slightly to avoid pinching.
Make sure you’re using the correct valve for your rim and then insert it.
Put the entire inner tube inside the tire so that it fits inside the rim.
Take care not to pinch the inner tube when installing it.

Installing the inner tube

Start installing the tire at the valve.
Finish installing the tire across from the valve to avoid pinching the inner tube.
Never install your tire with a tool or a tire lever, as you risk pinching or puncturing the inner tube.

Installing the tire

Carefully inflate your tire to the pressure recommended by the manufacturer (visible on the tire sidewall in PSI or bars: 1 bar = 14.51 PSI).
Regularly check that your tire is in the correct position as you inflate it.

Inflating the tire

To avoid punctures from pinching and for the best tire performance, we recommend checking your tires and inflating them to the suggested pressure before every ride.
