My personal experience after 17 y. driving xc90 2.5t AWD and trust me tried so many different models.
For snow of fresh by night 60 cm in St. Mortiz Switzerland Alp few years ago all roads was closed by night towards Italy the only one pass 2200 m high crossing was open. New Goodyear Ultragrip SUV 235/60/18'' was so good that I that drive over 40 years on snow ice ect in Slovenia, Germany, Swiss never had.
All other cars was sliding like on ice we pass so easy and I enjoyed driving up and down. There was one Italian Bmw I told him to rotate car and to be able to go uphill to drive in reverse and he first moment looking on me like WHAT??? Yes try to believe I had in 1985 one Bmw 315 that I drive like this in mountains. LOL
Wredestein was good but not last long. Pirelly that you mention also didn't lasted to me more than 22000 km and than never again same as Michelin 21000 km. Too soft for heavy front of XC90.
The second recommendation that I proved to made over 8000 km is that I rotate tires every 5000 km in cross x if possible depend of tires. Trust me help prolong duration few thousands km 100%.
This is Julier Pass the best road in Europe ever. Summer or winter I love it.
Immagine you are in middle of Switzerland mountains and all roads out is closed. Than we waiting that at least a little bit is cleaned and pass 2200 m high cross...
Diavolezza 3332 m you need to visit if you are in Switzerland.
