Congrats! I also have saddle brown great choice I took delivery just before thanksgiving and mine came with the Michelins too. The specs are below. I don't have any complaints about road noise. I would drive the car as much as I could before your Saturday call. For one thing 150 miles might not be sufficient to consider the tires to be in optimum condition.
