Product Information
Full details
The Vittoria Air-Liner MTB Tyre Insert is designed for mountain bike riders—ranging from Cross-Country to Enduro—who want to maximize rim protection, enhance tire grip, and prevent flats while running lower pressures. By replacing a portion of the tire's air volume with a durable, high-quality polymer foam, it allows for a more stable and controlled ride on technical terrain. While it significantly boosts performance and protection, users should note that the installation process requires cutting the insert to size, which necessitates a one-time measurement and adjustment before initial use.

FAQs
Does the Air-Liner work with tubes?
No, the Air-Liner is designed exclusively for tubeless systems.
How often do I need to replace it?
The material is designed to last up to 2,000 hours of normal riding conditions.
Can I use any sealant?
You should only use ammonia-free sealants to prevent damage to the foam structure.
Does this insert change my tire pressure?
The insert takes up volume, so you may find you need slightly less pressure than you are accustomed to, though it doesn't change the physics of inflation.
Is it difficult to install?
The process is straightforward but requires cutting the insert to size. Following the provided instructions ensures a proper fit.
Will this protect against all punctures?
While it significantly reduces rim strikes and improves overall stability, it does not prevent all tread-based punctures, so a quality sealant is still required.
Troubleshooting
Difficult to seat the tire bead
Ensure the tire beads are pushed deep into the center channel of the rim all the way around before trying to snap the final section into place.
Sealant degrading the foam
Verify that you are using an ammonia-free sealant. Standard ammonia-based sealants can react with the foam material over time.
Insert feels loose inside the tire
Re-check the length of the insert; you may need to trim a small amount more to ensure a snug fit around the rim diameter.

Setup, Compatibility & Care
The Air-Liner is compatible with standard and tubeless-ready wheels. To install, you must measure the circumference of your rim and cut the foam insert to the appropriate length before securing the ends with the provided zip tie. It is highly recommended to use only ammonia-free sealants to ensure the longevity of the polymer foam. During the life of the product, inspect the insert during your routine tire changes. If you are not riding for extended periods, storing the bike in a cool, dry place will help maintain the foam's integrity. Always ensure your tubeless tape is in good condition before installing the insert to maintain an airtight seal.
