Soon I will be getting a 2022 GT2 AWD. I live in Missouri and we get snow from time to time. How does the car do? Are snow tires recommended. Thank you.
We get plenty of snow in AK. I also used to live in OK for a while and I travel to Texas at least every 3 mo, so I know about ice storms too.
For occasional snow, no, you don't need winter tires. For freezing rain and layers of ice, you really need studded tires at these vehicle weights to be safe. That's freezing rain that doesn't melt, but stays frozen. When those things happen, it's best to let them clear out before driving or be extremely cautious and stay off the roads as much as you can. True winter tires will be wasting away fast in warmer temps and often at those latitudes the ground is still above freezing when it's snowing and accumulating. You're driving in slush, but penetrating and a true winter tire won't do a lot more for you.
Where we find the winter tires make a big difference is on surfaces below about 20 degrees F and when driving entirely on a frozen surface. Many tires have warnings that they are compromised below 40F, but I've never found there to be certain death at that temp. Things like direct sunlight on pavement, the car coming from a warm area, and then friction will help heat them up a bit and it's just not certain death at those temps on normal tires. But many summer tires say to not drive the tire below 20 degrees, that's when they crack. All seasons? No problem. You'd have to be going way colder than 20F for all seasons to get bad.
With the low sun angle, snow and stuff that falls from the sky (rain even) just stays frozen on the ground and it never goes away till the sun comes back up enough in the spring. They can remove some of it, but a lot of it is impacted and they just can't keep up. In other places the "road" is just packed snow. It's a totally different dynamic then other places I've lived, where it snows, but the sun angle, ground warmth and other factors just don't put it over the edge. In many cases, unless you either have AWD or studded tires, you often can't get started at an intersection on the impacted snow/ice. It would literally take you the entire intersection light to creep the car through the intersection without spinning (which stops your forward movement). We also get the "black ice" that your parent's always warned you was lurking behind every curve. That's frost on the road, it's similar to freezing rain, extremely slippery. Our ground temp stays cool in the winter, so even when it rains, it'll turn to ice at night. One time I witnessed the temp dropping while I was driving in the rain, on my studded tires. The rain changed over to freezing rain and instantly cars were going sideways all over the place. Armageddon scene.
I know you can have those cold Canadian storms and the temp can drop for quite a while, but I see those as mostly temporary and IME winter tires are for places like CO high country, Lake Tahoe/high Sierras, Montana/Wisconsin/Michigan, places that get and stay cold. Then it makes more sense to get winter tires. If I was you I'd stick with AS for the winter, get some nice summer tires for the summer. Life is too short to not ride on summer tires and then you won't be wearing either very fast.
I was stuck one time in Texas with 4" of freezing rain. We just had to wait days before it melted out. I did drive (carefully) to the supermarket, but it was mostly a "wait it out" deal. Places like that don't have snow and ice removal equipment and again, that's where you really need studded tires to be safe. Winter tires wouldn't help much and winter tread wears fast when it's warmer.
