I leased this car in February 07 and have about 6 months left on a 36 month lease. I have just put on my third set of run flat tires (at 30,000 miles). I wish I had checked the reviews of this problem before I purchased the car. There are thousands of people who swear they will never buy or lease another bmw because of these miserable tires. They are expensive, and ride like a truck.
