I chose this tire based on the other reviews indicating how much they improved the ride compared to previous generation run flats and I am NOT disappointed. My car came with OEM Continentals and had 36k miles and a reasonable amount of tread left on them when they were replaced. The main reason for replacing them was to improve the ride, and it's been well worth the expense. I feel like I've got a new car. Rumble strips and expansion joints that used to be jarring are now just a distant blip, and although I'm not a speed demon to begin with, I do have a little fun with corners occasionally, and I've noticed no decrease in grip, even though the tires are still quite new. I'll try to remember to update this review after a few thousand miles with additional comments. For now, I rank them as highly recommended!
