Michelin PS4S Rotation and Butt Dyno

[x35250]

I recently rotated my Michelin PS4S tires from side-to-side on the front and rear axles. The car feels slower since rotating the tires. These are not directional, so I'm not sure if I am just imagining this. The butt dyno says the car is not hooking and moving as well as it did before the swap.

I searched the forums already and see mixed reviews. Some people say BMW recommends against rotating the tires at all. They likely won't last longer than 15k miles, if that. Others are saying it is fine to rotate between the same axle for longevity.

Is this all in my head? Might it get better once the tires wear a bit more going the opposite direction as before?

Best to keep the tyres in the original motion direction on these, suspension,camber and road angles 'shape' the tyre into a certain pattern.
