## Overview

The Tannus Armour Tire Insert is a patented, lightweight polymer foam liner designed to provide up to 15mm thick puncture protection for mountain, gravel, fat, and e-bikes. It installs tool-free between tire and tube, adapts its density based on tire pressure for optimal grip and shock absorption, and allows continued riding even after a puncture. Reusable and recyclable, it offers a quiet, comfortable ride while preventing flats caused by thorns, goatheads, and other hazards.

## Description

The effective puncture protection system TANNUS Armor offers all-round protection against punctures, cuts and bruises! The system is installed very easily and without tools between tires (free choice of tires and tread pattern!) and tube. The outside of the hose is thus enclosed and thus protected. At the thickest point the puncture protection has a thickness of 15 mm, on the sides and in the rim area 2 mm. Depending on the tire pressure, the Tannus Armour changes its density and the thickness adjusts. If the air pressure drops, the Armour still acts against deformation and still offers high grip and low rolling resistance. It is therefore possible to continue driving at a reduced speed even if the hose is defective. The special high-tech polymer foam also provides good shock absorption while driving and the material is very light and recyclable. Another plus point is the reusability.

## Features

- Made of very light high-tech polymer foam - patented Aither 1.1 technology
- Very light weight, reusable and recyclable
- Very simple and tool-free installation between bicycle tires and bicycle tubes
- Quiet and comfortable driving experience - good shock absorption, good grip and low rolling resistance
- Support for the entire tire: at low air pressure, the Armor acts against deformation and at higher pressure it adjusts its thickness

## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    So far so good
  

*by B***R on Reviewed in Canada on 1 April 2024*

My ebike has 20x4 tire and I've had three Flats on the rear. A bit of research later an I picked up some Tannus Armour and some Slimed. I installed it on my rear tire in under an hour, not too hard if you follow the instructions, and so far so good after 3 weeks.

### ⭐⭐⭐⭐⭐ 







  
  
    Effective on goatheads.
  

*by T***N on Reviewed in the United States on 4 September 2024*

I have had this tire armor for 30 days without a flat. That's never happened before. Before I started using this brand of armor, I couldn't get through more than about two days max, and sometimes multiple flats per day. They're expensive, and a real pain to install, but once installed they have protected my tubes, and I ride a lot. The goatheads are so bad where I live, and have proven brutal on bike tires, yet these really did the trick. Gotta say thanks!

### ⭐⭐⭐⭐ 







  
  
    Purchase for Hubby
  

*by K***Y on Reviewed in the United States on 21 August 2024*

Doesn’t take up space. Good for quick flat fix. Easy to use. Good quality, I recommend.
