if you want better ride and to be less-susceptible to pothole induced damage, you want to go with a higher aspect ratio tire. because there is only so much real estate under the
wheel arches, this usually means stepping down in
wheel size. My '15 5.0 has 19" wheels all around. I think that moving downwards to a 17" or 18"
wheel, while increasing the aspect ratio of the tire would bring me closer to the same overall height and circumference of the original
wheel. not sure if a 16"
wheel is possible due to brake rotor size, but generally smaller wheels allow for more tire, which will get you what you are looking for.
