Don't ever do this when it gets below 30 after snow. Frozen snow mounds will destroy your car instantly.
Yes that's a good point! It was above 30 F today. Soft and wet snow. I know because I was out shoveling it.
Sorry, but I have lived in the snow belt my entire life and used mostly all- season tires and never been in the ditch. Perhaps you need a driving lesson
.
Dedicated snow tires are better, but they have disadvantages too. Especially when the weather gets mild and/or there is no snow or ice on the ground.
Not being in a ditch shouldn't really be the metric of a good winter tire. There are many advantages to snow tires. Better traction, better acceleration and handling, less chance of sliding or losing control, and less chance of crashing into other people and causing damage or injuries. This is all assuming common sense driving. Obviously there are certain things snow tires can't save you from, like driving unsafely in the first place.
But, there is no question that they are all-around better than all-seasons. I know some pretty damn good performance all-seasons exist, but the ones that come on our cars are not them. I don't think snow tires have disadvantages, either. I'm talking in a place that gets snow and has consistently cold temps. If the weather gets regularly mild it's time to change them out for something more appropriate. A few mild days isn't going to negatively affect traction much. It just might wear your tread a bit quicker. And snow tires
certainly offer all their benefits when there isn't snow on the ground. It has to do
much more with the rubber compound than the tread pattern. Non-snow tires will be much more likely to break free on cold dry roads.
Not trying to argue but I just strongly feel they are worth it depending on where you live and depending on your car. My wife's car just got rear-ended by a FWD car with normal tires due to black ice. It's not fun. Accidents happen but there are way too many cars out there unequipped to handle the weather.
