How to measure tyre wear
To measure the wear on your tyres and to know when they need replacing, you need to inspect the tread. The tread comes into direct contact with the terrain you are cycling on and therefore determines your tyre's performance.
A tyre needs to be changed when the centre knobs are worn down to the same height as the side knobs.
How to remove a tyre
To remove your tyre, first deflate the inner tube until no more air comes out.
Once deflated, use a tyre lever to remove the tyre from the rim.
How to fit a tyre
To put your tyre back on, first start by placing one side of the tyre into the rim. Next, inflate your inner tube to approximately 30% before putting it into the tyre (inflating it beforehand reduces the risk of pinching the inner tube). Then, place the other side of the tyre 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 tyre and the rim.
How to inflate your tyre correctly
Inflate your tyre carefully. The recommended pressure is indicated on the side of your tyre as well as on its product sheet (available online).
Before each outing, make sure that your tyres are at the correct pressure for your ride.
Tip from the pros
When inflating your tyre, be sure to inflate it to the correct pressure for the terrain you will be riding on and especially the weather conditions. When riding in rainy weather, lower the tyre pressure to increase the tyre's traction. When riding in dry weather, you can increase the pressure for better performance.
