For those of you who are still debating which tires work best, here is a true life experience.
My wife called me to state that she had a flat left-rear tire on her CLK55 Cab while heading home on the beltway from Kensington, MD to VA. I asked her what happened and she said she was going about 70 (yeah right) and "got a funny feeling in the car". I asked her if she lost control and she said NO (thank God, the car I can replace, but she is irreplacable). She didn't know how to use the jack and spare and wanted to know what to do. I told her to sit tight. I arrived to find the rear tire shredded from the center of the side-wall on both the inner and outer walls. My wife said she drove for about 2 miles (at 70 mph) before she pulled over to see what the problem was. I couldn't believe there was no damage to the wheel. I had to move the car further off the highway before attempting to put on the spare (a very nice full size one). I noticed that the side-wall attached to the bead would fold out and protect the wheel as it came in contact with the road and this is what saved the wheel from major damage and the car from losing control. At that point I decided no matter what draw back these tires may have, this was the slam dunk event that confirmed my decision to replace the tires with the same Michelin Pilot Sport's. Now this may be a fluke that the wheel survived, but it's enough for me (I can buy a lot of tires for the cost of one of those rear wheels).
