Just switched from Pirellis to PS4S...

and holy crap. The car is way quieter now, and the ride is so smooth. I had no idea how bad the Pirellis were until this afternoon. I simply can't understand why BMW would choose to put such a sub-par tire on these cars. \_(O_o)_/

I did that swap on my G12 750i and agreed, major difference in ride quality and performance.

If you don't know, with the purchase of those Michelin tires, they provide 3 years of roadside assistance if you ever get a flat. Plus few other benefits worth knowing.
