Renewable-material tires

Trendsetter dB Super E-spec tires from Yokohama are comprised of 80% orange oil and renewable raw materials. The company's super nano-power rubber (SNPR) compound derived from orange oil, natural rubber, and other components offers the E-spec low rolling resistance, contributing to improved fuel economy. SNPR compound operates in two modes: steady/straight driving and active driving, which includes cornering and braking. At steady mode, heat generation is constant and the compound decreases rolling resistance. During active mode, orange oil properties generate heat to improve grip. Four circumferential grooves allow water to escape the tread area for wet traction, and a twin rail stability rib maintains road contact, improving lateral stability and uneven wear. A lightweight inner liner improves air retention; variable tread sipes increase surface contact; and a sound-deflection sidewall decreases road noise by creating vibrations at a different frequency than the vehicle.
