IRC Aspite Pro (tube-type)

Notify me when this product is available:

The Aspite Pro is IRC’s high-end tube-type tire.

All Aspite Pro tires have X-Guard and Aero fins. The RBCC version uses a softer, grippier compound in addition to having RBC mixed into the compound. 


Puncture resistance and side-wall durability come from our X-Guard Belt,  a 40x40 TPI anti-puncture barrier.


All Aspite tires have “aero” fins along the beads that create a smooth transition from rim to tire, reducing air drag. This unique feature reduces air drag by as much as 4 percent when compared to conventional tires.

Rice Bran Ceramic Compound (RBCC)

Rice Bran Ceramic is derived from everyday ordinary rice. What we do to it, however, is anything but ordinary. We take rice bran, or the outer husk of an individual rice grain, grind it to a fine powder, mix it with a thermoset resin and super-heat the mixture. After cooling, the resulting material is pulverized to create millions of porous “balls,” each covered with semi-rigid spikes extending in all directions. We then knead the ceramic rice bran balls with rubber and mold it into tire tread. Once assembled into tires, the tiny spikes on the surface of the balls grab the road surface, increasing traction, while the pores wick water from the road surface and create a larger tire-to-road contact patch.
