The Potenza RE960AS Pole Position RFT replaced OEM Potenza previous generation summer tires on my 2007 BMW 328i with sport package. I was considering Michelin Pilot Sport go-flat tires, but I do like the run flat concept. These tires give a softer, smoother, quieter ride than the originals. They work well on wet pavement and seem to corner about as well as the OEM tires. The Tire Rack video helped me decide. I am looking forward to about twice the mileage.
