I did a fair amount of research on mini forums and other internet data and most everyone was very happy with the Continental Extreme Contact DW tires. I was AMAZED at the quiet ride. I purchased the car with @35000 miles and the original run-flats had already been replaced. The tires that were on it seemed pretty good on dry roads and cornering was never a problem, they had a little roll at max cornering speed. While I havent gotten to spend a lot of time cornering with the new tires they seem way more stable back and forth cornering.
