I’m in MD, and we don’t get much snow but the temps do wacky things. Winter performance tires are a better option than dedicated snow tires for me.
Im in VA and i feel the same about our bipolar weather. Some seasons its warm, some extreme cold and random blizzards periodically. Can never really tell what winter is going to be like the next year.
I would be curious to see that, because I don't really believe that. I used to have a Porsche Cayman, and one early spring track day, it was around 20F in the morning when we arrived at the track. During the first couple sessions, I had astonishingly little grip. ABS would activate easily, and I could kick the back end out easily in corners with a bit of throttle (which was normally not a problem with that car). Once it warmed up to ~40F by the late morning, the grip increase was very substantial. I've never experienced a similar sharp grip falloff on all seasons.
Now, I absolutely believe that you can safely drive a summer tire in cold dry conditions. However, I would bet that an all season will grip better below 30-40F.
I don't believe that either...but that's just my opinion. Sometimes at a stop and have the wheel cocked all the way to back up or go forward, i would feel it slipping trying to inch up lol. Its like running on ice with no skates.
OP. I've had the MSS and ran for a year ~30k miles. Gripped very well but never really pushed it to the limits on wet terrains.
Currently running Continental extremeContacts this summer because i wanted to try something with a little higher tread ware because tires aren't cheap...will switch over to the MPS4s for the next daily tire.
Picked up some RE71s for the track and really curious about how much sticker they are then the continentals.
For winter, i'm running Dunlop SP Winter Sport 3D and lasted for about 4 seasons. Now just took them off the car, i've noticed some pretty worn camber wear. I'm pretty sure if i pushed one more season, i'd probably blow or show some cords but we'll see. Figure most of the tread got ate when our "winters" had lots of warm days. Will probably look into the X-ice/WS80 for my area but in yours, i know some ran the LM32/LM60s before they stopped making them. there'sa LM01 now and i wonder how those are. Maybe might want to try out the PA4s like the others mentioned. All depends on your needs/wallet.
