Sometimes a tire can feel sloppy, but when put to the test it'll put down just as fast if not faster lap times. Even so some don't like "the feel" as it does not inspire confidence.

It's also worth reminding, the MPSS tires for the M2 are bespoke whilst the MP4S are an "off the shelf" general tire. This also plays a factor in how well the tire handles and performs.
Interesting thread, and an interesting perspective here. So many here are saying that the PS4S are the successor to the PSS for street driving. Are you suggesting the PSS have stiffer side walls giving better handling but slightly less comfort?
