Tannus Armour is an outstanding tyre insert that offers full - bead 360° puncture protection for all riding levels and styles. Crafted from a patented multi - cell foam compound named Aither, it's lightweight, flexible, and extremely durable. This foam insert sits snugly between your tyre and inner tube, providing 15mm of top - side puncture protection and 2mm of sidewall protection against sharp objects and rocks. It cushions the inner tube on impact, preventing pinch flats and protecting your rims during hard hits. Thanks to its sidewall support, Tannus Armour stops tyre buckling in fast corners, allowing you to run your tyres at lower pressures: 25 - 30 PSI for City/Commuter/Gravel/Touring and 15 - 20 PSI for MTB. Installation is as easy as fitting a regular tyre and it requires no maintenance. Features include: 90% puncture elimination, increased grip at lower PSI, vibration absorption for a smoother ride, minimized drag for fast rolling, the ability to ride up to 10km/h even with a flat, and quick, maintenance - free installation.

Using Tannus Armour is a breeze. First, just like installing a regular tyre, put the Armour between your tyre and inner tube. It'll fit snugly and start protecting your tyres right away. When it comes to tyre pressure, for city, commuter, gravel, or touring rides, keep it between 25 - 30 PSI. If you're into mountain biking, set it at 15 - 20 PSI. That way, you'll get the most out of the Armour's features. There are a few things to keep in mind. Make sure you choose the right size of the Armour according to your tyre and tube. You can check the size table in the product description. Also, even though the Armour can prevent 90% of punctures, it's still a good idea to carry a repair kit just in case. As for maintenance, the best part is that Tannus Armour is maintenance - free. You don't have to do anything special to keep it working well. Just enjoy your rides with less worry about flats and rim damage.
