Though, I'm not at all pushing them then. The dedicated summer tires start to go downhill a lot by even like 40 degrees, really noticeable.
You'd probably guess it but if you were racing or autocrossing you'll be disappointed, but for street driving they're A-OK. I think the peak summer grip being lowered is outweighed by being able to drive them in cool weather. In MN at least, we get a ton of those days.

Totally agree on the PS-AS4 tires....have them on our MINI Roadster S for all season driving here in Iowa. Also do a bit of autocrossing on them and they work for that application too..fun but not a dedicated auto-x oriented tire by any means.
Our '23 x3 M40i "lost" its runflats early on (
) and have Michelin Cross Climate 2 tires...they are a quiet, nice riding and responsive all season tire that does fine in the white stuff too.
