I've noticed that it comes with summer only tires. Given that it is used by at least some owners as a daily driver, does that really make sense on cars sold in temperate to colder climes?
 
When buying a Porsche, whether it is a 911 or a Cayenne or anything between, a Porsche owner is expecting great performance, including handling.

But if someone is willing to compromise that optimum Porsche handling, the Porsche configurator allows to opt for all season (jack of all trades, master of none) tires. And at least for the Cayenne and Macan, the configurator also includes the option of adding a complete set of winter tires. Not sure about the cars.
 
Yes, I've looked on the configuration for a base Macan and see the option for all season tires and also for the winter option
 
Does this mean you can't go north in the winter? Tires might fall apart, right?
Nah - you can go North, just like every other big city luxury SUV driver that shows up in Northern Vermont in the winter.

And then crashes because summer tires just don’t work at all in the cold.

And AWD doesn’t help you stop when you have zero traction.

I visited Stowe a couple of winters ago. It is a very nice place but if you don’t have winter tires, your travels will be unnecessarily exciting.

I wouldn't run it below 40 degrees and not drive aggressively right above that temp. My Cayman has just summer tires and doesn't get much winter use. It slides quite a bit at 38 and caught me by surprise and I don't drive aggressively at all. If there is snow on the ground summer tires are worthless.
 
Yes, noticed a dangerous precedent established on the sale of performance vehicles. Have saved a few friends who were not aware that summer tires on their new vehicle purchases where not suitable for winter driving here in Michigan. The dealer simply had not mentioned the issue. Probably because of a potential barrier to the sale due to the extra cost. Appreciate a good opportunity to upsell a second set of wheels/winter tires for those who go there.
 
I thought summer tires had a temperature range too. In other words, the rubber compound gets stiff under say 40°, which could result in sidewall damage.
Anytime I searched for replacement tires, all summer/performance tires stated a temp range.
 
I think Michelin standard for summer tires, is don't even touch them below -7C, the rubber is effectively frozen and will crack with any flexing. I've seen a couple "shattered" tires autocross tires come out in the spring, from someone dropping them in the winter in their garage when moving them. The rubber was still soft at 20C but the cracks showed that in the winter, the tires were like glass.

I got caught one fall with bfg/michelin summer tires on for a 32F rainy morning and once they became round, they did still work half decently, on a low power fwd car, but I wouldn't recommend it.
