Bridgestone debuted their Ecopia tire line, featuring a low rolling resistance design that helps to improve fuel economy without negatively impacting driving dynamics or braking. If you are not familiar with low rolling resistance tires, think about how the tires on your car or truck "flatten" a bit where they meet the ground while the car is parked. When you are driving, that same flattening occurs and that effect, in turn, creates drag that negatively impacts your fuel economy.
Bridgestone's Ecopia lineup includes the EP422 passenger car tire and the Dueler H/L 422 light truck and SUV tire. Both feature a low rolling resistance design that improves the drag, caused by the tire's natural properties, by 36% compared to traditional passenger car tires and 42% compared to standard light truck tires. This lowering of the rolling resistance by such a substantial amount reflects in fuel economy, improving the efficiency of the vehicle in question by 4%. So by simply installing the Bridgestone Ecopia tire on your car or truck, you can improve your fuel economy by 4%.
