Vittoria Air-liner Tire Insert

The Air-liner is compatible with both 27.5-inch and 29-inch wheels, provided your tire width is between 1.9 and 2.25 inches. It is designed specifically for tubeless setups, so ensure your rims and tires are tubeless-ready before installation.

Because the insert takes up space inside the tire, it can make the initial bead seating slightly tighter than a standard tubeless setup. Using a proper tire lever and ensuring the tire bead is pushed into the center channel of the rim will make the process much easier.

The insert weighs 90 grams per unit. While this adds a small amount of rotational weight, most riders find the trade-off in rim protection and the ability to run lower tire pressures for better traction well worth the minor increase.

No, the Air-liner is compatible with all standard tubeless valve systems. However, you must ensure your valves have cutouts or a design that allows air to pass through freely, as the insert sits against the valve base.

The durable polymer construction is rated for approximately 2,000 hours of riding. This lifespan will vary depending on the intensity of your riding style and how often you bottom out on the rim.
