If I turned the tire the opposite way, (rotating them), then, while it would wear even, it is against the way Michelin designed them to operate. I am sure they have different compunds on different sides of the tread, as well as different sidewall strengths as well which would be crucial for correct handling.

As a street driver I have never rotated my tyres (on my 987). I always just replace them. They wear slightly inside but not too far from equal. You may need a good alignment.

Other people have done this it seems so correct me if needed. I would guess I have directional tyres and they might not all be the same.
PS2s are not directional, so you're stuck. All you can do is move them side to side on the car, but that won't help wear. Directional tires such as the Bridgestone Potenza S-O2A that the OP has don't have an "outside" wall and can be flipped on the wheel.
