I'm a new ST owner and while I love the car, quite frankly I'm not a car guy--my thing is motorcycles. What should I be looking for in a more practical wheel/tire combo for a daily driver. My car gets used by others in the family, and those 17s and skinny tires are headed for damage. Should I get some 16s, 15s, or what? I would also like to get something more resistant to curb rash.
