There are few things in life better than riding a bike. These human-powered machines offer freedom, exercise, and a great way to unplug, well unless you’re riding an ebike of course 🙂. However, getting a flat tire during a ride can quickly turn a fun adventure into a stressful situation.

When I first started bike racing, I entered my local Cyclocross event. I vividly remember pulling ahead of the other riders in my category. I felt so proud of myself, with no one catching up to me as the finish line came into view. Then—pssssst—I got a flat. I then watched my victory slip away as other riders passed by. Having owned a bike shop and raced bikes for years, I’ve encountered every type of flat tire and solution out there. Over time, one brand has stood out for its innovative, flat-free technology: Tannus. With three distinct products:


They offer reliable solutions for every rider, from commuters to competitive cyclists. Let’s break down the differences and determine which flat-prevention solution is right for you.

TANNUS ARMOUR

Tannus Armour is a groundbreaking flat-prevention system made from a custom foam designed to shield your tube from punctures, covering it from rim to rim. Glass shards, thorns, nails, and even pinch flats are no match for this innovative technology. Developed by engineers experienced in high-performance foam products used in popular running shoes and football pads, Tannus Armour delivers lightweight durability with unmatched puncture resistance.

In addition to protecting against flats, Tannus Armour enhances ride comfort by absorbing vibrations and shocks from rough roads or trails. Riders often notice reduced fatigue in their hands and wrists, especially during long rides.

  • Who Should Use Tannus Armour?

    This versatile product is ideal for:

    • E-Bikes (Electric Bikes)
    • Commuters
    • Mountain bikers
    • Gravel riders
    • Kids' bikes
    • Casual bike path riders
    • Cruiser cyclists
    • Adaptive MTB BIkes (aMTB)
    • Adaptive Bikes
    • Trikes
  • How To Install Tannus Armour?

    Installing Tannus Armour is simple:

    1. Remove one side of your tire and take out the old tube.
    2. Insert the Tannus Armour liner.
    3. Replace your tube with one that matches the liner size (Tannus Armour reduces the internal volume of your tire, so a smaller tube is needed).
    4. Re-seat the tire bead on the rim and inflate to your preferred PSI.

TANNUS TUBELESS

Tubeless tires are popular for mountain bikers and gravel riders, but even the best sealants can fail to patch large punctures or gashes. Tannus Tubeless Inserts solve this problem while enhancing tire performance. These foam inserts provide run-flat technology, rim protection during hard impacts, and improved tire stability at lower PSIs.

With added sidewall support, riders experience better grip and control, especially in technical terrain. This makes Tannus Tubeless Inserts a top choice for aggressive riders who demand high performance.

Who Should Use Tannus Tubeless Inserts?

  • Mountain Bikers 
  • Downhill MTB
  • Enduro MTB
  • Trail MTB
  • XC MTB
  • Gravel
  • Cyclists looking to protect their expensive bike rims

TANNUS AIRLESS TIRES

Airless tires, also known as solid bike tires, eliminate the need for tubes or air entirely. You heard right, there is NO air in these tires.  Made from advanced lightweight foam, Tannus Airless Tires provide the durability of a solid tire with the comfort of traditional tube and tire systems, absorbing bumps and vibrations without the need for ongoing maintenance.

With no need to pump up your tires, replace tubes, or add sealant, Tannus Airless Tires are a true “set and forget” solution.

  • Who Should Use Tannus Airless Tires?

    These tires are best for:

    • Road cyclists
    • City commuters
    • E-bike riders
    • Kid bikes
    • Recreational riders

    While ideal for urban and road cycling, airless tires are not designed for off-road or mountain biking.

  • How Does It Work?

    Airless tires replace your existing tire and tube. Installation involves measuring your rim’s inner width, selecting the correct size, and securing the tire with pins that lock it into place.

  • Why Tannus Armour Requires a Smaller Inner Tube

    Why Tannus Armour Requires a Smaller Inner Tube

    Installing Tannus Armour for the first time can feel counterintuitive, especially when the instructions tell you to run a smaller inner tube than your tire size. But that size-down rule is exactly what makes Armour work. The liner takes up space inside the tire, changing how the tube inflates and how the whole system behaves on the trail. A smaller tube prevents folds, friction, bead issues, and the mysterious flats riders sometimes blame on the insert itself. When the tube matches the reduced internal volume, Armour can do its job: absorbing impacts, blocking punctures, and keeping the ride smooth and predictable. If you want easier installation, better flat protection, and long-term reliability, choosing the correct tube size is the key to making Tannus Armour perform the way it was designed to.

    The Case of the Missing Rim: A Tire Insert Investigation

    In this investigative deep dive, Wyatt Peterson from the Tannus Tubeless Division goes undercover to debunk the myth that tire inserts are a thing of the past. Despite rumors of "tougher rims" and "better warranties," the evidence from the lab and the field tells a different story.

    Featuring head-to-head data against competitors like CushCore and Vittoria, this report reveals how Tannus Tubeless Inserts allow for a 38% reduction in tire pressure without structural failure. From the grueling flint of Unbound Gravel to Ibon Zugasti’s legendary 65km run-flat finish in the Sahara Desert, the verdict is clear: Tire inserts aren't dead.
