Snow tires
Winter tires are a good idea for 4matics as well (though a 2003 500 is probably not a 4matic) as 2-wheel drive cars. A 4matic with winter tires will accelerate better than one without them (especially if the alternative is summer tires rather than all season), and when it comes to braking, a 4matic is no better than or different from a 2-wheel drive car.

Drove around all winter in my Dunlop WinterSport M3's. Made my car handle like my old Audi 2.8 Quattro. I drive a E55 and even with all that power and torque the M3's rocked!
