Aspite Pro RBCC tires are made with a new and improved RBCC tread compound that simultaneously reduces rolling resistance while improving road grip. Puncture resistance and sidewall durability come from our X-Guard belt, a 40x40 TPI puncture barrier over a 180 TPI casing. Rice Bran Ceramic Compound (RBCC) Rice bran ceramic is obtained from ordinary rice. However, there is nothing ordinary about what we do with it. We take rice bran, or the outer husk of an individual rice grain, grind it to a fine powder, mix it with a thermosetting resin and superheat 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 to form the tire tread. Once mounted on the tires, the tiny spikes on the surface of the balls adhere to the road, increasing traction, while the pores absorb water from the road surface and create a larger contact surface between the tire and the road.
