Air-Liner Light XC Tire Insert

Insert system for rim protection and lower pressure confidence.

Why I like it

The Vittoria Air-Liner Light inserts give me the confidence to run lower pressures without the constant fear of cracking rims — especially on rocky, technical race courses. I run them front and rear on my Epic 8.

While they don’t dramatically change ride feel, they allow me to get the most out of my tires. At rough events like Moab Rocks and the El Paso Puzzler, I felt like the inserts were quietly saving my wheels in the background — no cracked rims, no DNFs.

Even when I’ve cracked a wheel outside of racing while running Air-Liners, the tire/wheel still held air and got me home safely without needing to install a tube on the trail.

In My Setup

I run Air-Liner Lights in both wheels, always.
I target 12 PSI front / 13 PSI rear for smooth courses (Sea Otter, Leadville) using the Silca Tire Pressure Calculator as a starting point.
Easy install — just pop them in before mounting the tire and adding sealant.
Important: Use the Vittoria Air-Liner-specific valve stems — standard stems can get blocked by the insert.

Durability

Inserts hold up extremely well — I’d estimate 10,000+ miles if not damaged by extreme conditions.
Be cautious with some sealants: after experimenting with Silca Ultimate, one of my Air-Liners degraded heavily. I recommend sticking with something like Orange Seal Endurance.
