I purchased a mint condition 2011 X5 50 with the 20 inch wheel option two weeks ago from a Land Rover dealership in the Atlanta area. The X5 had 13,500 miles when I embarked on the ride home to NYC. While I very much enjoyed the trip, the one complaint I had was the the Bridgestone RFTs were loud at certain speeds and a bit harsh of a ride. Just today, I had a set of Continental DWS non run flat tires installed and I must say the improvement is stunning. The ride is softer (but not mushy) and the X5 just feels so much better. Perhaps my RFTs were worn (14,500 miles on them), but I am so much happier with these tires. I do have to now look into getting a space saver tire / jack kit.

I just wanted to let others who may be thinking of this tire swap, that I believe it is well worth it.

Thanks.
