Why Tannus Armour is a Game Changer

With the Tannus Armour 26 × 4.0 Tire Insert, you get more than just flat-free protection. It stops 90% of punctures, ensuring your ride stays smooth. This proprietary compound is torque-tested for e-bikes, ready to handle high-powered motors and the additional weight of fat-tire e-bikes. Plus, ride softer and grip harder by lowering tire pressure without risking rim dents or snake-bites. The Armour insert also serves as a rim-saving cushion, absorbing rock strikes and protecting your expensive wheels on rough terrain.

Product Features and Specifications

The Tannus Armour 26 × 4.0 Tire Insert fits 26” x 4.0 – 4.8” fat bikes and fat-tire e-bikes, with a minimum rim width of 19 mm inner. Each insert weighs about 480 g, similar to the weight of a water bottle. It's designed for a DIY-friendly install using standard tire levers, and a quick spritz of soapy water makes the process effortless. With this run-flat note in mind: the run-flat mode is optimized for standard MTB sizes, while fat tires gain huge cushioning but should be reinflated as soon as possible for full support.
