The Bridgestone Alenza Sport A/S RFT 285/45R21 113H XL is a premium tire used as original equipment on select BMW vehicles. It features circumferential and lateral grooves that evacuate water and resist hydroplaning, a long-wearing tread formulation, a low-profile sidewall, and a tread pitch that's computer tuned to resist hydroplaning. Its run-flat design also lets a driver keep going up to another 50 miles even in the event of total loss of inflation pressure.
