Use Less Fuel. Get More Green. The dB super e-spec is the flagship tire of Yokohama’s eco-friendly line. Its groundbreaking use of orange oil and other naturally derived components create an environmentally friendly, fuel-efficient tire that never compromises on performance. Yokohama engineers have created a highly effective tire with incredibly low rolling resistance. Because lower rolling resistance translates to better fuel economy, it will stretch the fuel economy of fuel-efficient vehicles even further. The dB super e-spec is built in a zero emission plant; one more example of our eco-motion philosophy - Yokohama’s global commitment to the environment.
