Just came back from taking a few photo's and -1 Celsius(30.2 F) is pretty cold this morning (thanks Al Gore and Greta)
The new Contis TS860S do their best but traction issues galore Got rid of the PA's and got me some Apex wheels.









Cheers

Hey, great photos.

I am picking up my M2C in 2 months, and the weather will be below 0 here in Canada.

Will it be safe for me to drive on the highway(about 130km)?

only if the road is dry and there is absolutely no ice.

otherwise you should mount snows.

Love it. More pics of the Apex's?

Which Apex wheels? Did you need spacers?

If you're going to drive it home highly recommend you take a couple of PSI out of the tires for added grip. Better safe than...

I'd personally be scared driving on the summers in below 0, Celsius or Fahrenheit.

It's not ideal, but it's totally doable. Summer tires stop in a shorter distance in the cold than either all-seasons or winter tires so long as the road is dry. Sounds counteractive, but there are actual real world tests that actually demonstrate this. Summer tires however are dangerous in the cold if the roads are wet or have any snow on them, in that instance you should not drive the car at all.

No they just fit perfectly, I have the Blue Brakes.

Apex 19 inch 8.5j 245/35 R19 V square Conti TS860S. Just a tad 'bigger' tyre sidewall than the oem PA 235/35 19s square setup.

Exactly, look at the Sportauto M2Comp laptime @ Hockenheim GP, PSS but an outside temp of just 1 degrees Celsius(zero is freezing temp) almost freezing, when a PSS is warm it's super grippy on dry roads.

Conti TS860 are generally seen|(overhere, German tests fwiw, because Conti is German lol) as the 'best' overal wintertyres (just like Alpins)

But on a dry winter road nothing beats a PSS in this case.

There's a lot of concessions with wintertyres: braking distance/traction on dry roads/sloppy road/steering feel, TS860 has it all(vs PSS)

This is true as long as you are above the Tg of the PSS. I am not sure they will get hot enough to perform well in random emergency stops and sedate driving depending on the ambient temperature. So, while they may be fine for driving hard or the track, they might not be great for daily driving. If I had to guess, Michelin Pilot A/S 3+ or similar is the probably the best tire in cold (clear) conditions.

Some tire manufacturers are recommending just the opposite.

That recommendation is for winter tires not summer. Makes sense to me as winter tires have sipes which is part of the reason they grip so well in snow and ice (aside from softer rubber compound), but that comes with a cost in relation to handling. Slightly over inflating winter tires would make them more responsive.

Lets not forget that manufactures recommend you do not drive on summer tires when the temperature is below 40 degrees Fahrenheit due to the possibility of the tire compound cracking. They also become hockey pucks in the cold which will limit traction to a dangerous level.

This review demonstrates summer tire braking in cold yet dry conditions. Start watching at 8m44s

Oh, my mistake, I didn't read the other users response properly.

Correct, that's related to the glass transition temperature (Tg) which I mentioned.
