Tannus Aither 1.1 Solid Foam Bike Tires

solid bike tires made from state-of-the-art aither compound

Tannus bike tires are a solid foam bike tire made from a state-of-the-art micro closed cell polymer resin called Aither – a patented lightweight foam that looks similar to the material used in many lightweight sports shoes, using a special foaming technology that produces a very durable long lasting foam suitable for use as a bike tire.

new aither compound

The Aither compound Tannus tires use has been through several iterations – it’s now lighter and 15% more efficient than the previous Aither compound. In addition to being more efficient, the new compound also offers a softer, smoother ride that’s more similar to a standard pneumatic tube and tire than ever before. Aither represents a revolution in solid tire technology by creating a lightweight tire that has similar performance to a pneumatic tire without all the drawbacks.

reliable

Tannus tires are pretty much the most reliable out there. Leave your patch kit and tire levers at home, and hit the road to work or to play without fear of popping a tire.

comfortable

Aither 1.1 is engineered to achieve higher shock absorption and better ride efficiency than older Aither compounds and other solid tires.

lightweight

In practically all cases, the weight of a Tannus tire in the rim is less than a typical tube and tire.

safe

Tannus tires have been certified through an independent testing provider. The tires achieve incredible durability and ride quality, and stay securely in place on your rim with locking pins.

locking pin system

A Tannus tire locks on to your existing bike rim using a patented locking pin system. Each tire comes with different sizes of locking pins to mount the tire to your rim. Simply select the pins that match your rim width, and the tire will lock on

compatibility

Whether you are looking for a good training tire for your next road race or triathlon, or simply want a reliable tire for your daily commute, you can’t go wrong with Tannus. Install Tannus tires on your bike and you can ride through all types of road debris with impunity!

Tannus are designed primarily as a commuting tire, so they’re not so much viable as a mountain bike tire or for many electric bikes. They work best on hard ground like dirt, pavement, and gravel.

Tannus tires are great on:

  • Road bikes
  • Hybrid bikes
  • Any of our non-electric Tern and Brompton bikes
  • Brompton electric bikes
  • BMX bikes
  • And more!
