Generally, I would favour winter tyres, unless you absolutely need 4wd all-year round.
Factor in that a 4WD car is more complex (ergo, expensive – bit like automatic gearboxes cost more) and they are also heavier, which along with the way the work, means the use more fuel. So, if you only need 4WD for occasional bad/inclement weather, you are paying a lot extra for little benefit.
Winter tyres you can keep locked away in storage, have them fitted for winter driving and then swap back when the seasons change. As they aren’t used all-year, they will last you a long, long time – and you can also buy snow chains for really bad weather.
I hasten to add that if you do get 4WD, if there is snow/ice, you should still be taking every precaution and that might include winter tyres and/or tyre chains. Don’t assume 4WD on standard tyres and normal driving is okay.
If the weather is really bad, I don’t venture out, even if I think the car can handle it. I only go out for essential journeys. Why? I trust myself, I drive appropriately for the conditions, but it is a risk at the end of the day and I absolutely do not trust every other road user to drive safely or maintain control.
Best of luck whatever you do!
