How to install Armour

How to install Armour

1. Inflate the inner tube slightly
Inflate the inner tube slightly. This makes assembly easier.

2. Evaluate the side wing cut
For some tires it is necessary to cut the side wings of the insert slightly so that they do not bend inwards during assembly. Place the insert inside the tire and make sure that the side wings of the insert do not protrude excessively from the tire. If the lateral wings are in excess, use scissors to trim the lateral wing of the insert on both sides.

3. Install First Bead of Tire and Armour
Place one side of the tire over the bead of the rim. Insert one side of the Armour inside the tire and over the rim.

4. Insert Inner Tube
Insert the inner tube valve through the rim valve hole. Place the inner tube inside the Tannus Armour. Make sure the Armour wings are not folded.

5. Mount Armour Into the Rim
Place the remaining exposed Armour flap over the rim under the bead.

6. Finish, Check, and Inflate
Secure the remaining side of the tire beading into the rim using a tire lever if needed.

Check that the tire has been installed correctly before inflating. Make sure the tire is not pinching the tube or the Armour between the tire bead and rim.
