The optimized tread design and the decreased tire weight manage to lower the rolling resistance. The contact between the casing and the tread lessens the tire's overall weight and ensures constant road contact, which eases the driving pressure off the tire. This reduces the rolling resistance, which is the force determining how much energy the vehicle needs to keep the tires in motion. The lesser the rolling resistance is, the lower the vehicle's fuel consumption and CO2 emissions will be, making the tire environmentally friendly.
