I was very, very disappointed to see that BMW installed Dunlop run flat tires on my 2012 535i. I had extremely poor performance from TWO sets of Dunlop tires on my E60 BMW. The first set wore out in 10K miles. The second had to be replaced due to wear after 11K miles. I did not realize how adversely the Dunlop tires affected the ride and handing of my BMW until I replaced the Dunlop tires with another brand (Bridgestone). BMW should drop Dunlop as a tire supplier. Dunlops must be the cheapest tires BMW can buy.
