Air-Liner MTB Tire Insert

Developed in collaboration with Deaneasy, the Vittoria Air-Liner MTB Tire Insert is the ultimate tire accessory for mountain bike tires. This innovative foam-based tubular insert for tubeless tires is a breeze to install, and does its job exceptionally well of protecting the rim, enhancing overall grip, and preventing punctures on some of the roughest and rowdiest trails.

Made from a new-generation polymer, the technical foam Air-Liner allows for lower tire pressures, prevents burping and bead-breaking, and and absorbs high-frequency vibrations for a smoother ride. While this polymer is slightly dense, it more than makes up for extra weight with incredible resistance to rocks and trail debris. Two continuous carvings—one on the top and one on the bottom—run the length of the Air-Liner to make room for the air and sealant within, and to better support the tire. Plus, installation is exceptionally easy thanks to the included zip ties and smooth cut-ability of the foam.

Love air liners

I've put it through the wringer
Size Bought:
Mtb & gravel version
6' 1"

I now have these one my mtb & gravel bike & will never ride without them. Been using them for 4-6 months with no issues. I love that the mtb version acts like a volume spacer in the tires calming tire rebound & allowing lower pressure with tire roll.

Best thing since suspension

I've put it through the wringer
Size Bought:
5' 11"

My wife and I have these installed in our DH bikes, E-bikes and our endro bikes, would not ride without them in the gnarly terrain we ride in. we can ride with far lower tire pressures for the best traction and reduced tire squirm, totally sold on these, one thing is though every once in a while we need to take them out and shorten them a bit as they seem to grow and then rattle a bit in the tire plus the valve core can block up and I need to poke a old spoke down to clear them, small price to pay for the protection and performance they offer, highly recommended
