i completely agree and am on the same page. I asked prior to purchase and was told the nonPP tires were rated as all season. It seems to be a point of confusion among the folks staffing both customer service and the spaces. And there’s no online info about the tires through either Polestar or Michelin so there’s really no way we could have made an informed purchase here.

I’m in not as cold an area so this only affects me for the few occasions I do a winter road trip. Since that’s at most a few days a year, if I can reasonably handle those days just taking it easy on the accelerator (which one should do anyway in slush/icy conditions!) then I’m fine. I’ll stress test this soon and report back.

in your situation I’d consider investing in winter tires and switching between summer/winter as needed.... or just getting all seasons.
I thought a bit about making a fuss to Polestar that they should provide all seasons for the 19” and even replace mine for free given their essentially false advertising. But I calmed down a bit from that at least when I first thought about it. If I get into uncomfortable situations this next trip I might reconsider

Just saw your post here @polerad .
Same story as under “Canadian tire specifications thread”. It’s clearly confirmed now that we are systematically being given the wrong information. This is no longer a standalone case. We honestly should hold ground. Summer tires in wet and cold conditions are just not as safe !

If you want to make a fuss, I'm right there with you. I may be doing so without you....

Count me in...

For the stock Michelin Primacy 4 tires of the 19" wheels, what is the lowest temperature/most precipitation we can reasonably use them in without substantial safety concerns?

If the weather is above freezing (0C/32F) and dry is that OK?
What if there's a bit of water on the road and we're at >0C? What about if there's some light snow on the ground?
Does anyone have any direct experience here yet?
Do we have any technical data from Michelin on these tires to go off of?

I've so far driven in the 30s-40sF/0-5C dry weather, and 50sF/10-15C light rain, and haven't noticed anything concerning. But I have a lead foot and like to drive on the twisties - so without some more guidance I could end up inadvertently in a bad situation.
Am I being overly anxious here?

I am gaining a quick education on summer vs winter tires as I've only ever had all-season tires supplied on my cars, and have only really driven in mild/warm climates. The little winter driving I've done has been in cities/suburbs and likely without the proper equipment as one does in the US. I have never had a 'performance' car and specifically chose not to go with the Performance Pack to optimize for comfort, practicality, and anti-faff. This is all now unexpected faff.

As you know, I've been swapping sets of summer and winter wheels for years now and it's worked well for me... It's given me that extra confidence that if I drive carefully in a snowstorm, I've got the right tires to back me up. Maybe I'm extra cautious because about 25 years ago I was driving on snowy/icy roads. I checked my braking ability on a flat, straight bit with no traffic coming and some wide shoulders. All was good. But then I went over a rise and was coming down a north-facing, mild decline. Despite my attempts to steer into the skid and despite lots of snowy parking lot practice, I couldn't get my front-wheel-drive Honda under control as my wife and I skidded sidewise, off the road, and into a telephone pole. It was a slow-speed crash at less than 10 mph, I'm sure. Wiped out the driver's side door but didn't do much more. Except, I think, that it resulted in some permanent damage to my wife's confidence in my driving abilities.

At that time, I wasn't up to speed on tires as I am now. I don't know what tires they were, but they were likely some sort of all seasons.

So I think we can only go by what the tire manufacturers and reviewers tell us: that summer tires, driven below 40 degrees Fahrenheit lose their grip and, furthermore, that the tires themselves can be damaged as the rubber becomes hard and brittle. All seasons are better, but they're a bit of a compromise.

If you're occasionally caught in bad circumstances, I think you can mitigate the problem by driving super cautiously, as if you could lose grip at any second.

Having two wheel sets is a pain to store away and a bother, perhaps, to switch out. It's also an extra expense to get a second set of rims. (The extra rubber is no extra cost providing you keep the car long enough as one set isn't being worn down when the other is on the car and vice versa.) However, with practice, a jack, a torque wrench, and a few other basic tools, you can swap out the wheels in about an hour and know you're doing all you can for your safety, that of your family, and that of those you share the road with.

Bummer of an answer, eh?

Michelin says that their summer tires grip best in termperatures at 40ºF and above: "Summer tires are designed for year round usage but should not be used during the winter season where temperatures are colder and approach freezing consistently as their performance would be less than optimal."

Where "less than optimal" becomes "a safety concern," I don't know, though. Depends a lot on the circumstances.

Let it snow - part deux

Will I get back in one piece is next question! Careful Rodders!

Just switch the traction control off and floor it, the collision avoidance will save you....

Does anyone know where the M+S is mentioned on the Michelin Primacy Tour A/S
i was chatting on the michelin website with an agent and he told me that it was on the tire but I could not find it
