The RFT sizes are engineered to allow for up to 50 miles of driving at 50 MPH (80km at 80 KPH) with zero air pressure. The Run Flat AZ850 offers an affordable option to the overpriced original equipment tires found on many performance SUV, such as the BMW X5, without compromising on performance or quality. The AZ850 RFT also offers an enhanced safety option to those drivers who are looking for the security of a run flat tire, even if it was not original on their vehicle.
The unique compound and tread design of the AZ850 were specifically engineered for the contemporary performance utility vehicle. The result is a rubber compound that helps reduce rolling resistance, which, in turn, allows the tire to run cooler at high speed. High-tensile steel belts and jointless nylon bands increase stability at high speeds and provide secure braking, handling and durability.
