The evolution model with 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.

TECHNOLOGY

RICE BRAN CERAMIC COMPOUND

Rice Bran Ceramic is, as its moniker suggests, derived from simple, ordinary, everyday rice. What we do to it, however is anything but. Rice bran (or the outer husk of an individual rice grain) is ground to a fine powder, mixed with a thermosetting resin, and super-heated. When cooled, the block is pulverized to create millions of porous, ball-shaped structures with semi-rigid fingers extending in all directions. These Rice Bran Ceramic "balls" are then kneaded with the rubber and molded into tires. The spikes which extend from the RBC reach out and grab the uneven road surface for increased traction while the pores will wick water from the road surface to create a larger tire-to-road contact patch.

 

NR-TEX(NATURAL RUBBER) INNER AIR SEAL SYSTEM

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.
