As for your situation, I think Mike hit it on the head. It's not so much the size of the tires, it's the age and wear that's the problem. My friend bought an '02 S four years back with 15k miles on the clock and original Pirelli P-Zeros. They were hockey pucks; loud, no grip, just terrible, even though they had considerable tread left. I introduced him to my tire guy and he had a new set of Michelin Pilot Sports installed...the difference was night and day (these are 18s, mind you). As Mike said, rather than change tire specs, put on a fresh set of tires (your choice) with a proper alignment and you'll be very surprised by the difference.

Best of luck and enjoy the Box!

Confirmed. A good set of fresh quality rubber will be the cure. Old tires just suck. If the car is an "S" the factory 16s won't fit around the larger front brakes.
