With the same impact resistance and tubeless-ready beadlock as the mountain-bike Air Liners, the Vittoria Air-Liner Gravel tire insert brings impact resistance, puncture protection, and performance-boosting stability to knobby tires on the skinny side. On square impacts, the Air-Liner’s resistance ramps up while it compresses to prevent rim strikes and pinch flats – essentially acting like a shock absorber installed in your tire. In addition to big-hit resistance, the Air-Liner Gravel allows you to run a lower PSI, enabling your tires to absorb stutter bumps that would otherwise filter up through the bike.

The Air-Liner Gravel provides a smoother ride by reducing the static from gravel chatter and minimizing rider fatigue caused by vibrations filtering up through the seatpost and handlebars. Its profile reinforces the sidewall for stability while cornering and locks the tire against the rim bead. This design maintains the tread's contact with the ground, ensuring responsive traction while climbing and braking. The result is a tire that delivers no folding, no burping, no sluggishness, and no flats, providing enhanced performance and reliability for gravel riders.
