RBCC technology

The RBCC rubber compound was developed by IRC and its performance has been proven in numerous races. The Formula PRO TUBELESS RBCC shoulders are layered with RBCC compound for high grip performance and the center tread is composed of hard compound which strikes a balance between wear-resistance, grip and rolling resistance.


To bring the advantages of a latex tube to a tubeless tire, IRC developed a new high-elasticity tire liner based on natural rubber which offers lower energy loss, reinforced with silica. Despite being slightly poorer at retaining air than the butyl rubber used for typical liners, air retention is sufficient, especially for tubeless construction.
