Vittoria’s mountain bike rim protection offering comes in the form of the bright green Airliner tire insert, retailing at $54.99 USD. We put it to the test inside a Maxxis Minion DHR II Double Down Casing tire on a rear 27.5″ Nukeproof Horizon V2 alloy rim. I rode this combination over my regular 19-21 PSI range and, to be thorough, dropped that to 12 PSI later on to ensure I was achieving frequent bottom-out, really putting its pinch-flat protection capabilities to the test. Here’s how the Vittoria Airliner MTB Tire Insert fared in our hands.
Review: Vittoria Airliner MTB Tire Insert
The Vittoria Airliner is composed of a dense, closed-cell polymer fashioned into a tubular shape with deep, wide channels running its full length. Each insert will fit 26”, 27.5” or 29” wheels; it is shipped to fit a 29er but is easily cut it down to fit the smaller wheel sizes with the use of a sharp knife.
Inside the tire, it is positioned such that one of the channels interfaces with the rim, while the other points upwards to the underside of the tire’s tread. We tested the Medium Airliner, measuring it up at 44mm/~1.7″ wide and 40mm deep. This one is recommended for tires from 2.3″ to 2.6″ wide. Vittoria also sell a small Airliner (35mm wide) for 1.9″ – 2.25″ XC/Marathon tires, a Large (50mm) for use with 2.6″ – 2.7″ enduro tires, and an XL (55mm) which is really only for use with plus-size tires.

The idea is that, in a pinch-flat scenario, the Airliner provides cushioning between the tire and the rim, protecting it from dents or, in the case of carbon rims, a crack. Pinch-flat protection isn’t the only claimed benefit, though. Vittoria also say the Airliner is designed to enhance ride performance by allowing the tire to remain stable and controlled, even at low pressures.
Upon impact, the corner edges of the channels flexing first, with the force progressively building to the thicker portion as the tire is compressed. Vittoria say this allows the tread to remain flexible, increasing traction, without sacrificing impact resistance. It is also marketed as a run-flat insert, too.

Installing the Vittoria Airliner
First, full disclosure. Due to some unfortunate OTBs over the last few years, a few key ligaments in my fingers and thumbs are compromised in their ability to withstand the loads associated with tire insert removal and installation (it’s OK, you can put your violins away). Lucky for me, the very capable hands of mechanic Tom Williams were available to help in this regard.
