Technical Information

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. Indeed, by being directly in contact with the terrain on which you are riding, it's the element that will determine the tyre's efficiency. 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 the tyre back on, place 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. On the other hand, when riding in dry weather, you can increase the pressure for better performance.
Tubeless Ready
This tyre can also be used as a Tubeless tyre (without inner tubes) when fitted to a Tubeless rim. Apply a special Tubeless liquid sealant to reduce the risk of punctures and improve air tightness. Preferably use a compressor or a high-pressure pump to inflate tubeless tyres. Tubeless Ready optimises grip and offers outstanding comfort.

En mojado y sobre gravilla suelta tienen poco agarre, pero traccionan bien en otros terrenos y tienen muy buena resistencia a los pinchazos. Talonan con facilidad y su precio es imbatible

Response of the brand
hola .
Sentimos mucho los problemas ocasionados por el neumático , te recomiendo que para los problemas que nos comentas y en rutas que lo requieran quites presión a los neumáticos para mayor precisión y agarre , si están con mucha presión no actuaran como es necesario. Si ya tenias en cuentas esto y los neumáticos no cubren tus necesidades puedes hacer una devolución o cambio del producto .
Gracias por tu comentario ,
