Frequently asked questions
What is Tannus Armour?
Tannus Armour is an insert that sits underneath the tire and over the tube. It offers puncture resistance, comfort, and enhanced riding capabilities.
Tannus Armour is made of a patented material called Aither. It’s a high quality foam-like polymer that offers vibration damping, a smoother ride, and puncture resistance.
Without Tannus Armour, your inner tube is much more exposed to sharp objects and debris. Your rim can also be damaged from hard impacts. Tannus Armour protects both your inner tube and your rim.
Will Tanus Armour work with tubeless tires?
We recommend not running the armour in a tubeless set-up. By using a tube you get improved puncture resistance and the full benefits of a smoother ride and no-hassle that you don’t get with tubeless.
We offer Tannus Armour Tubeless for tubeless set-ups. You can finding it by clicking here.
Can I ride flat on it?
One of the great features of the Tannus Armour is that if you get a flat during the ride you can ride a few miles without hurting your rim.* However, if you do get a flat please avoid rougher terrain.
*Does not apply to the follow sizes: 20x3.0-4.0, 20x4.1-4.8, and 26x4.0-4.8.
What PSI should I run?
Tire pressure is a personal preference depending on size of the rider and riding conditions. However, adding Tannus Armour does allow you to run lower pressure which gives better control, and comfort. We recommend starting out 5-10psi lower than what you normally ride and go up or down from there based on the ride feel you enjoy.
Does it compress after use?
The armour will compress some after it’s installed depending on the pressure of the tire. The higher the psi the more condensed the Armour will become. If you wish to keep the Armour as thick as possible then maintain a lower psi. You may also deflate your tire if you’re not going to be riding for a longer period. This allows the Armour to rebound back to its original size.
