I can’t say if anyone needs winter tyres or not. Different driving conditions, different cars, driving needs etc. all help determine what you need.
If you live in Tampa FL your needs may be different than North Dakota. Some people have ice problems others snow some drive freeways others back country roads. What you need I could not say.
I do have one universal comment. Stay safe! If you are not sure it is safe to drive, then don’t drive.
Always keep in mind that the point of any trip big or small, is to return un-harmed. If the weather is really bad, it is wise to consider not making that trip. Also remember that it is more important to be able to stop on time and to avoid getting into the ditch, than having a car with 4WD and super snow tires that will get you out of the ditch, when you should be worried about avoiding going into the ditch.
