Tannus Tire is a South Korean company who specializes in the manufacture of tubeless, solid tires. Since development of the company’s first prototype tire in 2004, Tannus has continued to improve their designs, with innovations such as a patented pin locking system, which safely holds their tires to a regular clincher rim.

Fast forward to February 2015, when Tannus is set to launch the company’s latest development, the Aither 1.1 road tire. The Aither 1.1, borrowing many design cues from the Aither 1.0 tire, features considerably less rolling resistance than the older model. The company claims rolling resistance of the Aither 1.1 closely compares to that of a regular pneumatic tire (tire and tube)…

Tests against a competitor’s pneumatic road tire with identical power output reveal travel speed to be marginally slower, with a loss in speed of approximately one kilometer per hour. So why would you want a tire that is admittedly slower? Due to the fact that the Tannus Aither does not use air to hold it’s shape, it is impossible to get a flat. Realistically, we’re thinking most cyclists will prefer the performance of standard tires, but for those who hate to break out the pump on the rare occasion they’re riding that bike in the garage, the convenience could easily be appreciated.

The Tannus Aither series of tires are constructed from an ultra-light polymer, that contains no rubber, but with a similar pliability, in addition to being 100% puncture resistant. Thanks to the pin locking system, the tire can be safely attached to any standard clincher rim. Additionally, the new 1.1 tire is guaranteed by Tannus to last up to 6,000 miles (9,600 kilometres) without losing more than 1.5mm of tread depth. Skidding is not covered by the warranty, so behave yourselves!

Tannus recommends the Aither 1.1 for training or commuting, sans the hassle of tire levers and pumps.
