I am north of you and I have been driving Caymans for ten winters. I have a second set of rims (18") and have always used winter tires. Between a lack of availability of winter tires in the required size and the fact that I only drive it on nice days, I went with the Michelin PSAS last year. I still use HP summer tires on my 20" rims during the warmer months. The AS tires are as good as I need in the winter - with ice patches always possible, I don't push too hard.

 

Opposite coast here, but similar climate. I ran PS AS3 year-round on my 911, and am running Toyo Proxes Sport AS (20" sizes) on my Cayman. For anything but extreme driving, today's good A/S tires will be fine for all year.

 

Maryland. Michelin Sport Alpin winter tires. More for the cold than the slush. Prefer not to coat the car in road salt.

 

Similar region and similar question from myself. I'm in the 5mm range on my PS4S (after 8k miles, somehow) and have been considering what to do when replacement time rolls around. High performance all seasons sound like a solid choice, given that I also plan to drive the car on salt-free winter days. I never get close to the limits of grip of the PS4S on the street, so HPAS probably will do just fine.

My only concern with the HPAS is how they'll hold up to occasional autoX use over the summer. I already get some minor scalloping on the PS4S and worry that AS tires will be even less heat tolerant. But I haven't been autoXing so much as to feel that a second set of wheels is justified. I guess if the choice is between summers + winters and HPAS + 200tw tires, I'd get more use out of the 200tw set vs winters. Still, the space and money for a second set is no joke!

Kind of in the same bucket. I've lucked out finding spare sets of wheels on FB Marketplace, but trying to decide myself on whether if I should just put some A/S on and use my spare set as autocross wheels (vs putting winters on them.) I generally avoid driving if inclement weather is going to be crazy (mostly because I dont trust anyone else on the road 😂) and I'm not driving at 9/10s on the street.

I guess another option is to have three sets of tires (summer, winter, and autox) and swap them back and forth.

 

Kansas City area here, so similar to slightly colder climate. I use All seasons (Michelin pilot sport) as “winter tires” as I never drive this car in the snow but want the compound better suited to colder weather. I switch back to my summers once the threat of temps under 40 or so is gone.

The all seasons are definitely squishier and less responsive. I wouldn’t be happy using them year round.

 

Really that bad for puttering around on the street + having a little fun? I figured I'd never be pushing the tires hard enough on the street to notice sidewall roll. I'd probably have to pair with a 200tw set for auotX, but was hoping to get away with a set of HPAS for street use all year.

 

I'm in SE (North Carolina to be specific) and snow is rare here, but a lot of clear cold days where it can be in the 20s

I'm at 6/32" of tread, so I'll be looking at a set of tires early next year (CGTS 4.0)

my choice (Ultra High Perf All Season) will be Continental Extreme Contact DWS 06 Plus
-I have these on my other two vehicles and have used them for many years

 

I bought some 19” wheels used and run Michelin PS4S in the colder months. Swap back to the stock 20” when it warms up.

 

Just for clarity, did you mean PS4A/S? I can’t imagine driving the PS4S’s in the winter…..

 

Of course not bad and it’s all subjective, and I certainly appreciate the all-seasons compared to what pure winter tires would offer, but the advantages of the sharper turn-in, more precise on-center feel, and better traction of the summers are not subtle to me. I do push my car pretty hard on curvy roads.

 

I appreciate all the discussion on this. I’m thinking the best route is to buy a second set of wheels and for the climate here, mount some Michelin Pilot Sport all seasons.

When are most of you making the switch? I’d guess early November through end of March is probably the best time for the all seasons around here.

 

I just run the Michelin PS4A/S year-round. For me, they are that good. The PS4's were just used for autocross and yes they do need to be replaced with something more appropriate. That's a next year expense.
FWIW

 

It depends on how you plan on using your car. l'm in Northern VA and keep the summer tires on year round. During the winter, I take the car out for a run on days that the temperature is around 40 degrees or higher, which is quite often. If you're using it as a daily driver or need to use it from time to time regardless of the temperatur, get all seasons for the winter. (And, of course, summer tires are potentially lethal in the snow.)

...and in the cold. They turn to bricks at really cold temperatures. Plus you will damage them.
