Snow tires lol...

Well, studded tires are not fun to have on pavement, specially the noise is pretty bad. In my experience, they are not that much worse on wet pavement, but I would say that also model has a lot to do with it. But for sure, they are not made for cornering on pavement.

My volvo has Nokian Hakkapelita's and they are pretty rough and loud on pavement. Can't remember which brand are the tires on CR-V, but they are a lot smoother and also provide a better lateral grip in the corners.

Once the winter hits here, bye bye dry pavement, welcome the snow, slush and ice!

That's my issue. Most of my winter driving is on bare roads but when I need snow traction I REALLY need it.

On truly frozen asphault, winter compound > not.  Just before I put the Mustang away for the season, we had a cold snap where it was getting into the low 20s over night.  One morning I was driving to work at 6AM (roads were nicely cold-soaked and no solar loading to heat them) and when I pulled out onto the highway, the back end broke lose and I fishtailed under power.  Didn't accelerate really any harder than I normally would in dry conditions.  In fact, I took off from the stop in 2nd gear.  That was shod in some fairly grippy hi-po summer compound tires.  The performance all seasons I used to run on my Mazda likewise noticeably lost grip when the road surfaces got to be well below freezing.

Testing and my real-world experience says all-seasons beat snow tires' grip on any temp (or at least down to the coldest I've ever seen - say 15F) bare pavement. By a long shot.

But was the asphault actually 15F?  If the sun's out, asphault will be above freezing even in a 15F degree ambient air temperature environment.

Generally, yes (at night too).

C&D winter tire test: A/S stopped up to 30' shorter on 23F dry road vs. studless snows.

Done at 23 ambient air temperature, not 23 surface temperature.  If you look at the photos from the test day, it was pretty bright out.  Surface temperatures were likely north of 35F, perhaps as high as 40F, with solar loading.  I'd also point out that their "wet" skidpad was also reported at 23F.  A thin film of water doesn't stay water very long on 23F asphalt, so the surface had to be above freezing or their wet skidpad would have been an ice-rink.  That or they tested in salt water.

... now I've got the element to drive when it does happen.  I might just keep the summers on year round and get rid of my snow tires.

    I miss having seasonal cars...

Unless the car was driven at speed for a time, the tires would have been at about ambient temp, not road surface temp. Also, to me it doesn't look bright out and the ground is concrete (or at least not black asphalt).

I can see a pretty clear shadow of the car in the dry pictures.

Ambient temp was -9C, snow-pack on the asphalt with fresh powder above it, and snow tires ftw.

So we got a little dusting last night and my Potenzas RE670/970 w/e pole positions are horrible in this weather.

We had like a few inches here, and every car I drove wanted to slide off the road, with the exception of the Malibu with WS70s on it.  Shitty tires on everything else.
