The model's high speed performing capability and maintained optimal tire shape, under the high speed driving pressure, is the result of the nylon reinforced steel belt construction. The constant optimal tire shape prevents deformation during the tire's high speed performance, enabling its maximized performing capability. The special polyester cord body improves the driving comfort. It absorbs the shock of driving, which subsequently lowers the road vibrations felt in the vehicle's cabin, guaranteeing a comfortable driving experience.
