How to assess tyre wear

To assess your bike tyre wear, and subsequently know when to replace them, you have to inspect the condition of the tyre tread.

Among signs of wearing:

- a frayed tyre tread,

- a series of micro cracks,

- a tyre tread that is tending to flatten,

- the tyre casing is starting to show.



As many cases where the tyre is worn and must, therefore, be replaced.

How to remove a tyre

To remove your tyre, you have to completely deflate the inner tube. You will then be able to work loose the tyre from the rim using a tyre lever.

How to fit a tyre

Before fitting a tyre, start by firstly placing one side of the tyre bed in the rim strip. Once this is done, pre-inflate your inner tube approximately 30% before mounting the tyre (the prior inflation prevents pinching the inner tube).

Then fit the second side of the tyre bed in the rim, starting from the opposite side of the valve.Before completely inflating your tyre, check the inner tube is not wedged in between the tyre and the rim.

How to properly inflate a tyre

Take care when inflating your tyre. The recommended pressure is listed on the side of your tyre. Also make sure before each outing that you have the right tyre pressure.

Pro tips

When inflating your tyre, check you have the right amount of pressure adapted to the terrain you will cover and especially the weather conditions.

If riding in wet conditions, don't hesitate to reduce the tyre pressure to increase traction.

Conversely, when riding in dry weather conditions, you can increase this pressure.
