  • Nano Pro-Tech™ Tread Compound

    Improves rolling resistance and contributes to fuel-efficiency and CO2 reduction by controlling the interaction between polymer, filler materials and other rubber chemicals at the molecular level

  • Fuel Saver Sidewall Compound

    Helps lower rolling resistance by both returning more energy back to the tire and reducing heat generation as compared to a traditional sidewall

  • Silica

    Improves traction in wet conditions by increasing flexibility of tread compound

  • Recycled Ground Rubber

    Made from ground-up post consumer tires, it contributes to 5% of the tread compound

  • Circumferential Grooves

    The circumferential grooves help to channel water out of the footprint area to improve resistance to hydroplaning"
