Tannus Armour tyre insert offers 360° bead to bead puncture protection for all levels and styles of riding. It provides protection against sharp objects, sidewall cuts, rim damage and pinch flats.
Tannus Armour is a foam insert made with patented multi-cell foam compound called Aither which is lightweight, flexible yet incredibly durable.
Sitting flush between your tyre and inner tube, the Tannus Armour provides 15mm of puncture protection on the top, as well as 2mm of sidewall protection from sharp objects and rocks. It cushion the inner tube upon impact meaning there is never any contact of the tube with the rim, hence no pinch flats. The Armour also provide additional protection to your rims during super hard hits.
Due to the sidewall support Tannus Armour prevents tyre buckling under laterally-applied force in fast corners. This means you can run your tyre pressure considerably lower than you would for a standard tubeless set-up. For City/Commuter/Gravel/Touring: 25-30 PSI and MTB: 15-20PSI
