I got these Michelin Super Sports when I put on my aftermarket 19 Brabus wheels. They are solid performers and have a nice quiet ride, which compliments the car. Road noise is minimal, even when the tires are worn down. Driving style is moderately spirited, the car is a daily driver to and from the office, with a mix of street and hwy in Orange County, CA.
My issue is the tread life. I used to get 20,000 miles+ from the Michelin PS2 tire and the Goodyear Eagle F1. On these Super Sports, I only got 17,000 miles, and the tread is showing on both of the rears (E550 is a rear-wheel drive car). I'm going with another brand this time, most likely the Continental Extreme Contact DW.
