Falken RI130 Ecorun is a steer position commercial truck tire made for line haul and highway driving. With the all-new tread compound, Ecorun can offer more mileage without compromising fuel efficiency. The tire features an Advanced Stress Dispersion technology that spreads strain evenly across a wider tread surface that improves wear and maintains ideal contact shape with the road surface under different loads. The Contoured Shoulder Ribs flex under load to form a flat surface that promotes even wear and improves tire footprint. For additional flexibility, Falken redesigned Decoupling Groove using a teardrop shape at the base, which also reduces strain and prevents tearing. The Uniformity Safeguards ensures the tire maintains its consistent shape, extends tire mileage, and promotes healthy even wear. 4D Nano Technology added to provide longer wear and lower rolling resistance, while the Smart Shape Case Technology minimizes casing growth throughout the life of the tire for a consistent tire profile during loaded and unloaded driving conditions.
