TANNUS ARMOUR
STOP FLATS
ARMOUR HELPS YOUR RIDE
Armour improves every level of your ride, from rim to tire.
Armour provides additional sidewall support to your tire on hard turns. It also works with your tire to provide run-flat capability on regular tire sizes (Excludes fat tire sizes).
Armour protects with up to 15mm at it's thickest point. It wraps nearly 360° around your tube.
With Armour protecting your tube, you can run at lower PSI and increase your traction and handling.
Even your rim is protected with Tannus Armour. It will provide cushioning to the hard hits and protect against pinch-flats.

FREQUENTLY ASKED QUESTIONS
WHAT SIZE FITS MY TIRE?
Our Armour sizes are based on your tire size. If your tire size is 26x2.1 then you would select Tannus Armour 26x2.0-2.5.
If you need tubes you will want to use our size chart (above) to see what tube size you need. You will need a smaller tube size than what your tire requires.
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 5psi lower than what you normally ride and adjusting your psi up or down from there based on the ride feel you enjoy.
Fat-tired e-bikes shouldn't run too low (under 10psi) as this may not offer enough support or give the comfort you're accustomed to.
E-BIKES can run at normal tire PSI.
CAN I RIDE FLAT ON TANNUS ARMOUR?
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 following sizes: 20x3.0-4.0, 20x4.1-4.8, and 26x4.0-4.8.
