Before You Begin Installation

We recommend doing the following to help you install Tannus Airless Tires.

Remove from packaging and carefully stretch into a circle shape.

If possible, place in the sunlight or warm place to help with installation.

Remove the rim tape from your rim to give space for your new Tannus Airless Tire.


Airless Tires Installation

NOTE: We highly recommend you having your Tannus Tires installed by an authorized Tannus Dealer.

STEP ONE: Select Your Correct Pin Size

Use our Pin Sizing Chart to determine the correct pin color for your rim. As a general rule, the pin size is +3.5mm wider than your rim's width.

STEP TWO: Pin insertion into tire

After choosing the correct pin size, insert the pins flat side up into the pin holes. Check the pin orientation carefully.

Insert pins into tire as shown below.


Gently stretch the tire for easier installation. Take caution not to overstretch the tire as this could damage tire and may influence performance. 

STEP THREE: Mounting your Tannus tire

Once the pins are correctly inserted, mount the tire on the rim. Fixing one or two pins into rim will secure the tire and ease the mounting process. Mount the tire so that the pins are only showing on one side (figure A).

As seen in figure B stand the tool up with 70~80 degree and push down hard. If you feel and hear "Click" sound or vibration, the pin is inserted into rim correctly (figure C).


If your rim is shallow remove the rim tape before mounting the tire so there is enough room for the new tire to fit properly. 

If your rim is deep you may want to keep the rim tape on. If by chance you have already removed you tape and you hear a "Tick, Tick" when you ride, it may be that there is too much room between the tire and the rim causing the tire to float. In this case, remove the tire, put a rim tape on the rim, and mount the tire again.


STEP FOUR: What to check after installing

A. Make sure all pins are installed correctly. If any of the pins are showing repeat step 3. There should be no visible pins if the installation was done properly.

B. Check the tire balance. As seen in the figure below rotate the tire to ensure that the mid-line is straight and center. 

STEP FIVE: How to care for your Tannus Tire

Dirt and stains can be removed with a wash or wipe down of the tire.  For best results use a tire cleaner. 

STEP SIX: Removing your Tannus tire

Removing the tires can be difficult as they are designed to stay on the rim. It's recommended to visit an authorized Tannus dealer for the removal process.

Answers to 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.

Why get Armour?
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.

Tannus Armour Specifications
Tannus Armour weighs between 190-500 grams depending on the size. It provides 13-15mm of protection at it's thickest point and 2-5mm of sidewall protection.

How much does it cost?
Each insert is $40. So a set will cost $80.

Armour and tubeless
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.

Are they for road riding?
While they were designed for mountain bikes and gravel bikes, they are great for your commuter and road bikes. They will help with the puncture resistance and overall comfort.
