Loving this thread, a lot of arm chair drivers 😀
I can assure you that 2 winters on the front and 2 good tyres on the back work, having just driven back from skiing.
1 week in Chamonix, 5 days in Avoriaz, several times up at 4,000 feet+ and a 500+ mile drive back crossing the Jura [Lelex route de cret] with snow in the Haute Soane with several inches overnight in Luxeuil-les-Bains, The Vosges and Ardennes even in Holland with cars having difficulty in car parks.
