- 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.
How do I put sealant in my tyres?
There are two options:
- You can inject the sealant through the valve with a Presta valve that has a removable core. The advantage of this method is that it is cleaner. The sealant is injected when the tyre is already well positioned on the rim.
- The second option is to inject the sealant directly inside the tyre before mounting the second bead.
How often should I add or replace the sealant? Sealant remains effective for only a certain period of time, which depends greatly on the temperature, storage conditions, riding locations & frequencies, etc. After a certain period of time, the sealant dries and turns into a rubber film, or breaks into small pieces.
We recommend that you check and add sealant roughly every 3 months, depending on how often you use your bike.
