An ultra-lightweight insert that reduces fatigue, improves cornering, and helps prevent flats.


Not all tire inserts are created the same.

CushCore is no ordinary tire insert and is based on a new concept, tyre suspension. Any suspension system has a spring and a damper, and with CushCore, pressurised air in the tire is the spring and the CushCore tire insert is the damper.

Like traditional suspension, a constant damping force wouldn't work. It has to be dynamic. Suspension should be supple on small bumps but firm on the big hits.

CushCore responds differently depending on the tire load and scenario. The more the tire flexes, the more damping it provides.
