That's like saying what's the advantage of painting my blue car red. No advantage, just for looks

The sidewall of the tire will be shorter and the tread likely wider since it's lower profile, improving handling and responsiveness. It will also make the ride a bit harsher, will probably increase tire noise, and won't be as resistant to wheel damage if you hit something large.

15"
softer ride - lower cost for tires - better rim protection due to more rubber

17"
more responsive handling - can install larger rotors due to clearance - better looks for many people
