The Atturo AZ850 RFT tire is a performance tire for Sport Trucks, SUV's and Crossovers. This run flat model is engineered to allow for 50 miles of driving at 50MPH with zero air pressure. The AZ850 was specifically engineered for the performance utility vehicle with a unique compound and tread design. Integrity under hard cornering is handled by the large outer tread block while reduced noise levels and water evacuation are handled by the finely sliced inner tread block. Wet grip is increased by the four main grooves while directional stability is enhanced and improved straight line driving are handled by the center rib.
