It all depends on if they are all weather or all season. All seasons are gonna get you stranded in a ditch. All weathers such as the Nokian WRG-4 is a snow rated tire and it does a pretty darn good job. The all weathers are great when you commute on mostly paved roads that are plowed and salted often, and occasionally you go on some back roads where a snow tire is usually needed. An all weather gives you less rolling resistance than a dedicated winter tire, better gas mileage, but they’ll wear out in the summer faster than a standard all season. If you live out in the country or drive a lot of country or mountain roads, spring for a dedicated winter tire, like the Blizzak, the Nordman, or Hakkapelita. I’ve never run studs, but some people swear by them. Don’t run all seasons around here though. If for nothing else, it’s an unnecessary danger to put a tow truck driver in, when the situation could have been avoided. Even if you can drive fine with the all seasons, STOPPING in snow is much much better with winter or all weather tires. Do some research, go to dedicated tire shops, don’t buy stuff from the dealer unless it’s damn close to free.
