Air-Liner Tire Insert

Developed in collaboration with Deaneasy, the Vittoria Air-Liner 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.

  • Technical foam tire insert for added protection on the trail
  • Made for tubeless and tubeless-ready tires with sealant
  • Air-Liner adds grip, protection, and allows for lower PSI
  • Prevents burping effect and bead breaking
  • Cut edges of the tube according to size of your rim
  • Item #VIT003V

Pinch flat on day one

Familiarity:
I've used it once or twice and have initial impressions
Fit:
True to size
Weight
135 lbs

I got this after getting a my first pinch flat after a year of riding. I was a little paranoid, so I was running higher pressure (26psi) for my weight (135lbs). I was also checking my tire regularly after every run. After my last run, I ended up with a small pinch flat. Maybe it's coincidence, but my tire lasted only a day with this insert. Because the insert takes up so much volume the air volume in the tire is much smaller. So even a single burp can drastically reduce the pressure of your tire. Regardless of how it happened the insert didn't protect my tire from a pinch flat.

Still destroyed my rim

Familiarity:
I've used it once or twice and have initial impressions

I picked one of these up and installed it in the rear wheel of my hardtail. I usually run 25 PSI in my rear. I inflated to just over 20 psi with the insert installed and went for a test ride on a rocky trail. Within a mile of descending, I’d bottomed out and destroyed my rim. I don’t understand all the reviews gushing about running 10 or 15 PSI, as the liner didn’t do anything to save my rim even at a reasonably normal pressure. I know a lot of people swear by these, but it just flat out didn’t work for me.

Flat Protection at 10 PSI!! :O

Familiarity:
I've put it through the wringer

Finally got the Vittoria Air-Liner review for you guys! To start off, I am really happy with this product. Since I ride a hardtail, naturally I put a lot of abuse on my rear tire and having tubeless tires I was always worried about losing tire pressure and the tire popping off at lower PSI. Now that I've been riding with the AirLiner in the back wheel, it's given me a peace of mind while riding which gives me more attention to focus on the trails I'm riding and not worrying about my tire and rim. Even though I wouldn't ride the trails with only 10 PSI in my rear tire, while testing the low PSI on the curb and rocks - I couldn't even tell that I was running such a low PSI because it still felt super soft riding over the chunk. The vittoria air liner gives so much more cushion than Cush Core because it fills more of the tire and it's not just a rim protection piece. The design of the air liner is very ingenious and since I have been riding with it for the last two months, I have not noticed any bad side effects to having it in my tire. There is some added rotational weight, but that is not what concerns me because it is so little that I personally do not notice. I hope this review was helpful!

Installing the Vittoria Air-Liner

Installing the new Vittoria Air Liner 1) is extremely easy to install, and 2) it appears to give a lot more support and protection versus the CushCore counterpart. Looking at the cross section of CushCore I noticed the foam did not rise into the sidewall very much and I really wanted the extra protection in harder turns and holding the tire from rolling. I am not saying this to bad mouth CushCore! I really like their product! However, since Vittoria introduced this product at Sea Otter - I've been following their production and have been excited to try this out.

Better Traction and Rim Protection.

Well worth it!! Running lower pressures allows significantly way more traction. Added benefit is carbon rim protection when I blasting through a chunky-ass rock garden or bike parks.

Extra traction and protection!

Familiarity:
I've put it through the wringer

I've used these with 2.6 inch tires and they have allowed running lower pressures, getting more traction, and preventing rim strikes. The ease of install is much better than the cushcore system, though cushcore does ride great as well. Only complaint is that I've had issue with the valve getting blocked by the insert and have had to remove the valve core and press the insert out of the way. This happened both to myself and my buddy that has a set. A set of the cushcore valves would fix this.

Gotta Have It

Familiarity:
I've put it through the wringer

I just added a hardtail to my MTB quiver, and I have no intention of riding it any softer than I do my full suspension bikes. When rallying hard through rock gardens, or coming off drops / jumps without good landings, you need a little extra piece of mind that you are not about to blow up your $$$ rear wheel. This liner (while admittedly is a pretty expensive pool noodle looking piece of foam) provides that peace of mind, and offers additional damping on the rear tire that air alone can't provide. Should you flat, you can also ride out on this thing and not have to walk home. 200% worth the extra cost for the item, especially if you are pushing the limits of low PSI on a hardtail. You spent a bunch of money on those wheels, you can probably swing another 100 to make sure you don't wreck them. As Clayton mentioned, not difficult to install. A bit of a bear to get the tire bead seated fully when working around the liner, but by no means a show stopper. Probably took an extra 5-7 minutes vs set up of a normal tubeless tire. Edit - One year Later Stand by everything I mentioned above. I would not ride a "trail" hard tail without one of these installed. Full Stop. Your fork has dampening. On a FS your rear shock has dampening. On your hardtail, your rear tire is all the suspension you have. It should have dampening.

Hi Craig, Can you provide the wieght of these inserts for a 29er in the medium size

It's peace of mind. Getting a piece of someone's mind is pretty much the opposite.

Perfect

These tire insert are awesome. They are easy to install unlike a Cush Core and weight a lot less. Perfect for that little extra protection. Well worth it.

Hello Clayton, Would you run these over the huck norris's? Do they offer the same or maybe more protection than the huck norris's? Are these as protective as the cushcores and if not, are they alot less protective? Thank you and happy trails, Kelly

What size do I need for 28 mm rim width and 2.5" tires?

2.5”... Match the Tire WIDTH you require... They Are "Too Long" (to fit ALL Rim Diameters {622mm 584mm 559mm} WithOUT ridiculous inventory hassles)... be careful not to cut too much off when you insert the foam into tire, and trim the extra (it should fit without a gap and without buckling, slightly too long is better than slightly too short, yet it might not be an issue when you get to 'slightly')... CushCore is much harder to install and remove, yet is noticeably better while Riding, yet AirLiner is definitely Very Good... I am just an Engineer that failed to design something better than these inserts such that I will BUY vs. trying to compete in this niche market...
