3 seasons it wears 235-35-18 PS 4S and in late fall I pop on these 17" AS.
The car doesn't get driven much but here is what I notice most (especially late fall and early spring).
They still feel sporty, they grip on cold pavement much better than the 4S... They have a considerably harsher ride and they art way more "crashy" and loud. On the good side they actually function if there's a bit of snow or slush and unlike the 4S they stay pliable and grind frozen pavement.
I can't comment on wear because they don't get much use. They do however keep my summer car functional for the months when it's not the daily.
