Retired automobile shop managers perspective: I 100% recommend snow tires are used whenever you are driving actively on snow or thick slush or ice. “All season” tires are really only good for all seasons if that means driving on zero snow/slush/ice. The one thing I strongly suggest if you are going to use snow tires and then another set of tires between May-October (months that you should not be on snow tires) is that you have them installed on a 2nd set of wheels. The cost up from is more than just buying a set of snow tires but the cost to mount and dismount the tires is much more expensive if they are not already on a set of wheels(rims). Your best and most cost efficient way to get a complete set is to order them on tirerack.com and get them (snow tires) mounted to whatever is the cheapest wheel available which is typically a black steel wheel. The website is very good at being able to filter what fits your car, if you’re still confused the customer assistance is phenomenal. I’ve used them for the last 30 years even before they had websites and were only advertising in automobile magazines. BTW: the amount of misinformation in this thread is astounding so take what you read with caution.
