The SE comes stock with the 18” Carreras mounted with 5mm spacers so I don’t consider them +1. At any rate the ride and handling are perfect for me. My XKR was on 20s, our S5 is on 19s and the Explo is on 20s, all stock. We don’t know anything other than low profile in our garage for 3 season driving here in the Catskills. The Explo and S5 are on narrow, higher profile 18s with Blizzaks for the winter and we see no appreciable difference in ride quality. Dry handling is another matter due to the snow tires.

I typically run 34/39 lbs (f/r) on the 986. It’s a personal preference. In any case, you do have to really watch the potholes with any low profile tires, especially if you run lower tire pressures. For me, that’s the only downside.
