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 replaced when the centre knobs are worn down to the same height as the side knobs.
How to remove your 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 put your tyre back on
To mount your tyre, first, fit the bead (the flexible or rigid part, depending on the model, that determines the shape of your tyre) to the rim. Once you have done this, inflate your inner tube by approximately 30% before fitting it to the rim (inflating it beforehand reduces the risk of pinching the inner tube). Next, fit the second bead to the rim, starting at the opposite side to the valve.
How to inflate your tyre correctly
Inflate your tyre with caution. The recommended pressure is indicated on the side of your tyre as well as on its product sheet (available online). Also, before each outing, make sure that your tyres are at the correct pressure for your ride.
Tip from the pros
When inflating your tyre, make sure you inflate it to the suitable pressure for the terrain you will be riding on and, above all, the weather conditions you will be riding in. When riding in rainy weather, lower the tyre pressure to increase the tyre's grip. If riding in dry weather, increase the pressure for higher performance. Also, before each outing, make sure that your tyres are at the correct pressure for your ride.
Information / Concept / Technology
The Wheel Energy laboratory, certified and recognised by the leading global brands, measures several different criteria: grip, cushioning, resistance to wear, longevity, performance.
At B'Twin we design the tyres of tomorrow. Our R&D engineers create prototypes at our international headquarters in Lille, France. These are then tested in our laboratories and approved for use by our professional cycling team to ensure outstanding quality. This expertise is indicated on our line of B'Twin tyres with the label "DESIGNED IN FRANCE".
This is a stiff bead tyre, to avoid damaging it, do not fold it. Store it in its original shape.
For optimal performance of this tyre, we recommend you inflate it to a pressure of between 2.8 and 4.1 bars depending on the type of terrain. You should also check the carcass regularly to avoid any risk of a puncture or an accident.

I used these to replace the knobbly tyres that came with my son's Decathlon bike. These are far better for road riding, and I would recommend them.
