TIRE INSERTS

The original Air-Liner system for tubeless stability, impact protection, and compatibility with 26/27.5/29 wheels

Punctures are a fact of life, but the Air-Liner MTB keeps a mid-run flat from imposing an insurmountable time penalty, an auto-DNF, or a hike-a-bike to the transition. The Air-Liner’s high-density structure keeps your tire rideable for up to an hour after a flat – enough time to clear a stage or hustle back to the trailhead. Your ambitions don’t have to deflate just because your tire did.

The Air-Liner isn’t just an emergency flat solution – it also helps prevent punctures by preventing rim strikes. As it compresses, the polymer material ramps-up like a shock. Trail chatter is muted, root lattices are smoothed, and the big hits and square edges of rock gardens are cushioned. The Air-Liner’s cross-section keeps the tire’s contact surface fluid and flexible, but it also increases lateral stability by buttressing the sidewalls.

Technology explained

A high-density polymer structure gives the Air-Liner MTB all the qualities of a good shock: it mutes chatter and ramps up under big impacts, increasing ride comfort and preventing rim strikes. It also acts as a run-flat for up to an hour if you do puncture, and it has an install life of 2,000 hours. The insert’s cross section is compatible with all tubeless valves, keeps the tread lively, and reinforces lateral stability. The Air-Liner is compatible with all tubeless and tubeless-ready mountain bike tires and ammonia-free sealant.

Vittoria Air-Liner MTB

Vittoria were a little slow in getting back to me with a technical query about rim width but the answer was very honest. They said the wide rim and narrow tyre were not an ideal combination but that I would gain some benefit. I ordered anyway, at a heavily discounted price, and delivery was very quick (just as well because it was pretty expensive).
Compared to other liners I have seen used, the Vittoria was fairly simple to put on, following the manufacturer's instructions to the letter. So far I have had no issues with punctures. I can't say I have noticed much difference compared to my previous tubeless set up but I like the sidewall support and the reduced risk of pinch flats. If anything changes I'll do a follow-up review.

Great impact protection but….

I have these on both my bikes and the really do a great job protecting the rim. My only issue with these is that they stretch like crazy and they drink up scellant. I just had to re cut them after 2.5 months of riding and had to cut at least 4’’ off and had no scellant left. The sound they make when they are stretched is really annoying because it sounds like dribbling a basketball in the tire…
