Falken RI150 Ecorun is an all-position commercial truck tire engineered to maximize the mileage in regional haul applications. This tire is built to last. With its Smart Shape case technology, RI150 Ecorun minimizes casing growth throughout the life of the tire for a consistent tire profile during fully loaded and unloaded driving. Its 4D Nano technology along with uniform carbon dispersion makes it possible to provide longer wear and lower rolling resistance by controlling the size and even distribution of carbon molecules throughout the compound. The micro sipes along the rib walls ensure even wear by adding flexibility to the rib wall, while 3D wavy tread groove distributes stress evenly across the base of the tread to prevent cracking by stiffening the outside shoulders to add rigidity for improved handling.
