Inspect the tread to measure wear and to know when tires need replacing.
Signs of wear include:
- tread starting to fray
- appearance of micro cracks
- low tread depth 
- carcass becoming visible.
All of these indicate that the tire is worn and needs replacing.

How to measure tire wear

To remove your tire, start by deflating the inner tube completely.

Once deflated, use a tire lever to remove it from the rim.

How to remove a tire

To put it back on, place one side of the tire into the bottom of the rim. Next, inflate your inner tube to approximately 30% before putting it into the tire (inflating it beforehand reduces the risk of pinching the inner tube). Then, insert the other side of the tire into the rim, starting on the side opposite the valve. Before inflating the inner tube all the way, check to make sure it isn’t pinched between the tire and the rim.

How to fit a tire

Inflate your tire carefully. The recommended pressure is indicated on the side of the tire and on the product sheet (available online).
Always make sure your tires are at the correct pressure before heading out on your ride.

How to inflate your tire correctly

When inflating your tire, make sure you inflate it to the suitable pressure for the terrain and the weather conditions you will be riding in. When riding in rainy weather, lower the tire pressure to increase traction.
When riding in dry weather, increase the pressure for better performance.

The knobbly tread structure provides good traction on various types of terrain.

The structure of the knobs offers very little rolling resistance.

Designed for MTB bikes with 24" wheels, offering the best balance of features.

Replace your tire when the centre knobs are worn down to the same height as the side knobs.

To remove your tire, start by deflating the inner tube completely. 
Once deflated, use a tire lever to remove it from the rim.

Self-Repair

Section

Check the information indicated on the sidewall of the tire (diameter and width). For example, 26 x 1.90 means that the tire is 26" in diameter and 1.90" wide.
The dimensions in mm (ETRTO international unit) are also on the tire sidewall.
For example, 50-559 means that the tire is 50-mm wide with a 559 mm inner diameter (approx. 26 x 2.00).

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.
