The Vittora Air-Liner Tubeless Tire Insert is a high-quality polymer insert, which replaces a portion of the air volume in tires. This trait, combined with the shape, provides a tunable system that enhances your ride performances. The Air-Liner destroys the traditional compromise of stability vs. grip, and allows your tires to remain stable, grippy, and controlled, even at low pressures.
The Air-Liner is designed using a round cross section, with channels on the top and bottom. The top channel provides room for the tunable air chamber that sits directly beneath the tire tread. Upon impact, the corner edges of the channel flex first, and progressively build to the thicker portion, as the tire is compressed. This allows the tread to remain flexible, which increases traction, without sacrificing impact resistance. The bottom channel allows for easy fine-tuning of the air chamber, and allows for full compatibility of all valve core styles.
The Vittoria Air-Liner Tubeless Tire Insert is available in 4 sizes, and is compatible with all makes and models of tires. Small: 1.9" - 2.25", Medium: 2.25" - 2.5", Large: 2.5" -2.7", X-Large: 2.7 - 4.0".

This Victoria Airliner is one of the best things I've ever bought for my bike. I'm using the inserts since August 2022. I admit, it was a little chore to install it. But once I had it all together, and put the sealant in it was all smooth sailing after that. I still ride 200 miles a week and since I put the inserts in, I didn't get a puncture. I lowered the tire pressure by 5 pounds per wheel. I was afraid that the performance of the bike will decline. But I was wrong. The ride is now nice and smooth. I am an older rider. That's why I'm looking for a comfortable ride. I would recommend this Victoria Airliner to everybody, especially to older riders.
Super easy to install, and gives excellent rim protection! Riding primarily single track on my XC bike, with some huge roots and the occasional rock. I had a few pretty good dings on roots which led me down the path of a tire liner. Primary goal was rim protection, however the "bead lock" and run flat are nice bonuses. I was already familiar with the Air-Liner gravel version as I've ran those for the past couple seasons on my gravel bike thanks to a recommendation from the mechanic at my LBS. Decided to pick up these and have been great so far. Running much more comfortable pressures without fear of hurting a rim, and might just be placebo but I swear it feels smoother with less vibration as well. Thankfully haven't tested the run flat capabilities so far on the MTB liners, however they've saved me a few times on the Gravel bike.
These are great. Yes, they made installing the tires harder, but doable and worth the effort. Plus they're super light. I installed with Terravail Ehline tires and when complete, they were 3 oz lighter than my Maxxis Minions installed without any foam cores. And as a bonus they're removable and can be used again. I was able to remove the tires and air-liners without any damage to either.
