The All-New Tannus Gravel Tire Insert

With all the same excellent features you have come to know from Tannus, the new gravel insert continues to push the limits of comfort, simplicity, and performance.

Through extensive testing, Tannus has developed an insert that solves some of gravel biking's most common problems. Rim Protection, Flat Prevention, Shock absorption, and sidewall support.

Gravel Tire Insert

Rim Protection and Shock Absorption

Installing these inserts allows you to run at a lower tire pressure while also protecting your rims. Lower tire pressures mean better small bump compliance and increased traction.

Inserts for Gravel Tires

Flat Prevention

Tannus inserts prevent common types of flats like puncture or pinch flats. The tubeless version adds support to your tire that decreases your likelihood of flatting. The tubed version protects the tube from punctures and sharp corners. On the off occasion you do flat while using Tannus, you can run these inserts while flat and make it back to the trailhead.

Sidewall support

Tannus Inserts are designed to give additional support while cornering. The Flexible wing design adds stiffness to your sidewall so you avoid rolling your tire.

Tannus inserts are designed to help you ride more and worry less.

Tannus Armour Review: 7 Things Riders Should Know Before Buying

If you have been researching Tannus Armour, you have probably come across some different opinions about what it does, how it installs, and whether it is worth it. Most of that confusion comes from riders comparing completely different bikes, riding styles, and expectations.

Tannus Armour is built for one simple purpose: helping tube-based bikes prevent flats before they happen. That means commuters, e-bike riders, kids’ bikes, mountain bikes running tubes, city bikes, and everyday riders who are tired of dealing with punctures, pinch flats, and roadside tube changes.

Let’s walk through the biggest questions riders usually have before buying.
The Best Bike Flat Protection of 2026: A No-Nonsense Guide
In 2026, as bikes get heavier and torque gets higher, relying on "thick rubber and luck" is no longer enough. This comprehensive guide breaks down the science of Advanced Polymer Dynamics and how Tannus Aither 1.1 technology is redefining ride reliability across three distinct categories:

Tannus Airless

Tannus Armour (Tube Liner)

Tannus Tubeless
Why Tannus Armour is the Best Flat Protection for E-Bikes: A Deep Dive into Tire Reliability

E-bikes have revolutionized transportation, but their weight and speed make them "puncture magnets." In this deep dive, we explore how Tannus Armour solves the unique "physics of the flat" that plagues heavy e-mobility. Featuring a 3,000-mile cross-country case study and a technical breakdown of the patented Aither micro-cell polymer, we show how a 15mm foam shield can eliminate 90% of punctures.

Learn why standard tires fail under e-bike loads and how Tannus Armour provides a critical "run-flat" safety net for commuters. We also share expert installation pro-tips, including tube sizing and the "rebound rule" to ensure your ride remains smooth, stable, and, most importantly, unstoppable. Whether you’re a daily commuter or a coastal cruiser, discover the "fit and forget" secret to total tire confidence.
The End of the Flat Tire? Airless vs. Pneumatic: What You Need to Know

Tired of the "dreaded hiss" ruining your morning commute? This guide breaks down the high-tech shift from traditional air-filled tires to the Tannus Airless revolution. Using patented Aither 1.1 micro-bubble polymer, Tannus has engineered a tire that is 100% puncture-proof, thermally stable from -20°C to 60°C, and lasts up to 10,000 km.

We debunk common myths about weight and grip, while highlighting why airless tech is the ultimate "fit and forget" solution for E-bikers and urban cyclists. Whether you're looking to save time on roadside repairs or reduce your environmental footprint with 100% recyclable materials, find out if making the switch to airless is the right move for your ride.
Why Tannus Armour Requires a Smaller Inner Tube

Installing Tannus Armour for the first time can feel counterintuitive, especially when the instructions tell you to run a smaller inner tube than your tire size. But that size-down rule is exactly what makes Armour work. The liner takes up space inside the tire, changing how the tube inflates and how the whole system behaves on the trail. A smaller tube prevents folds, friction, bead issues, and the mysterious flats riders sometimes blame on the insert itself. When the tube matches the reduced internal volume, Armour can do its job: absorbing impacts, blocking punctures, and keeping the ride smooth and predictable. If you want easier installation, better flat protection, and long-term reliability, choosing the correct tube size is the key to making Tannus Armour perform the way it was designed to.
