- Inflate your tyre so that the beads are well positioned at the base of the rim. A characteristic «pop» sound may be heard, depending on the type of rims and tyres used.
- Inflate your tyre, without exceeding the maximum recommended pressure indicated on the side of your tyre. (Make sure not to exceed your wheel's maximum pressure, if applicable.)
- When the tyre is mounted, let the air out and add the sealant.
- Put in the amount of sealant recommended by the sealant manufacturer (the amount usually depends on the volume of your tyre).
- Place the core back into the Presta Tubeless Ready valve and inflate your tyre. Adjust the pressure according to your height, weight and riding style.
- Rotate the wheel to help the sealant covers the entire inner surface of the tyre. (A short bike ride will help distribute the sealant evenly throughout the tyre and maximize its sealing action. You should check and adjust the tyre pressure before every ride. Optimum airtightness may be achieved after several days of use (depending on the sealant/tyre combination)).
- Once the wheel is mounted on the bike, it is important to check the position of the brake pads in relation to the rim to avoid damaging the tyre.
Use of tyre sealant
Sealants are usually latex-based and have the added advantage of being able to seal punctures, providing a lasting repair. Unfortunately, these products have a limited life-span.
Why do I need a sealant? Tubeless Ready tyres are not completely airtight. You need to use a sealant to make sure that they are airtight.
Combining a Tubeless Ready tyre and a sealant provides better protection against punctures, and the sealant has a minor impact on rolling efficiency. This is why Michelin only manufactures Tubeless Ready tyres, rather than tubeless tyres, which you may have used in the past and which do not require a sealant.
Comment mettre du mastic dans mes pneus ?
Il y a deux possibilités :
- Vous pouvez injecter le produit d'étanchéité à travers la valve avec une valve Presta dont le noyau est amovible. L'avantage de cette méthode est qu'elle est plus propre. Le produit d'étanchéité est injecté lorsque le pneu est déjà bien positionné sur la jante.
- La deuxième option consiste à injecter le produit d'étanchéité directement à l'intérieur du pneu avant de monter le deuxième talon.
À quelle fréquence dois-je ajouter ou remplacer le sealant ? Le sealant ne reste efficace que pendant un certain temps, qui dépend fortement de la température, des conditions de stockage, des lieux et des fréquences de conduite, etc. Au bout d'un certain temps, le sealant sèche et se transforme en film de caoutchouc ou se brise en petits morceaux.
Nous vous recommandons de vérifier et d'ajouter du sealant tous les trois mois environ, en fonction de la fréquence d'utilisation de votre vélo.
