Just for clarity, is the consensus here that it's better to flip the tire 180 deg and keep it on the same rim, which would mean it's rotating in the opposite direction and flipping inside to outside, or swap it to the opposite side wheel (i.e. translation without rotation), keeping rotation in the same direction but swapping inside to outside. Seems like the latter would be less problematic in terms of tread pattern if they're directional, but if the pattern is intended to discharge water to the outside of the car, maybe the former is preferable.
