FAQs
How long does the sealant last?
The liquid sealant is designed to provide protection for the lifespan of the inner tube under normal riding conditions. However, performance can be affected by factors like temperature and time.
Can I use this tube with tubeless-ready rims?
This is a standard inner tube and is not intended for tubeless setups. Using it in a tubeless-ready rim requires proper rim tape and sealant application for a tubeless conversion.
What is the ETRTO size?
ETRTO (European Tire and Rim Technical Organization) size is a standardized way to measure tire and rim dimensions. For example, 50/62-622 means the tire has a nominal width of 50-62mm and fits a rim with a 622mm bead diameter (commonly known as 700c or 29-inch).
Can the sealant be replenished?
While the tube is designed with sealant, it is not typically designed for user replenishment. Significant loss of sealant or sealant effectiveness usually indicates it's time to replace the inner tube.
What does 'STD 48mm' refer to for the valve?
'STD' typically refers to a Schrader valve, which is a standard car tire valve. '48mm' indicates the length of the valve stem.
How does the butyl technology contribute to pressure hold?
Butyl rubber is known for its excellent air-retention properties. Combined with the liquid sealant, it creates a robust barrier that minimizes air permeability, keeping tires inflated for longer.
Troubleshooting
Inner tube loses air rapidly after installation
Check for a pinched tube between the tire bead and rim. Ensure the valve stem is straight and not damaged. Verify the tire and rim are free of sharp objects.
Sealant is not sealing small punctures
Spin the wheel to distribute the sealant. If the puncture is too large or the sealant has dried out, replenishment or replacement of the inner tube may be necessary.
Difficulty seating the tire bead
Ensure the inner tube is partially inflated to help seat the tire. Use tire levers carefully to avoid pinching the tube. Check that the tire size is compatible with the rim.

Setup, Compatibility & Care
Setup: Install the Michelin Protek Max inner tube following standard bicycle inner tube installation procedures. Ensure the tire bead is properly seated on the rim before inflating. Inflate to the recommended pressure range for your tire and riding conditions.
Compatibility: This inner tube is specifically designed for mountain bike tires with sizes ranging from 29 x 1.9 to 2.5 inches. It features an STD (Schrader) 48mm valve. Always confirm that the ETRTO size of your tire matches the compatibility range of the inner tube. Consult the specifications table for detailed size information. Example: The `Michelin Protek Max MTB Inner Tube - 29 x 1.9 - 2.5 (STD 48mm)` is suitable for tires listed with ETRTO sizes such as 50/62-622, 54/62-622, etc., within the 29-inch diameter.
Care: Periodically check tire pressure before rides. Inspect the valve stem for any damage or leaks. While the sealant is designed for long-term use, extreme punctures or significant air loss might indicate a need for sealant replenishment or tube replacement. Clean the exterior of the tube with a damp cloth if necessary.
