Etrto

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.

Inspect the tread of your tires to measure wear and to know when they need to be replaced. Signs of wear include:
 - tread starting to fray
- the appearance of micro cracks
- low tread depth - 
the carcass becomes 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.
Then separate the tire from the rim with a tire lever.

How to remove a tire

To put the tire back on, insert one side of the tire into 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 the tire with caution. The recommended pressure is indicated on the tire's sidewall and product sheet (available online).
Always make sure your tires are at the correct pressure before each outing.

How to inflate your tire correctly

During inflation, it is important to obtain the right pressure depending on the terrain and especially depending on the weather.
If you ride in rainy weather, feel free to lower the tire pressure to increase its grip.
When riding in dry weather, you can increase the pressure for better performance.
