Commercial vehicle tyres

摘要

The tire has a multi-layered belt (2) and a tread (1) that includes a radial inner tread base (7), which is formed from electrically non-conductive rubber composite containing silica, and a radial outer tread cap (6), which is formed from soot-filled rubber composite. Dynamic rigidity of the rubber composite of the base is smaller around 10 percent than that of the composite of the cap. Side walls (5) are formed from electrically non-conductive rubber composite filled with silica. A carbon center beam (9) is arranged in the base and connects a sub-structure with the cap.
