I use UniRoyal M/S Plus on my winter wheels, and I've driven the Scirocco over Wood Head and Snakes Pass in inches of snow in the winter.
I was passing stranded AWD road cars like X5s and TTs, also saw two stranded articulated lorries, a Police Ford Transit on its side, and various others in ditches and hedgerows.
My Scirocco is NOT an off road car, lowered and corner weighted on coilovers with chassis bracing and very nice paint, it's really not the car to take it in a snow storm.
Unless I drive on ice like Stig Blomvquist (I really don't) then it has to be down to the tyres getting me through conditions that had amateur and professional drivers in 2 and 4 wheel drives crashed or stranded.
I won't be doing it again unless I really have to, but it was the first time I'd needed winters in years and years, and I wanted to see how they performed.
In this case they were surreally capable.
