what's the benefit of using AS tires? Please name a single one, that is not related to having another set of wheels. In summer they wear out quicker and has less grip, especially in wet, compared to summer tires (the grip is still decent), but in winter they are basically useless.
Two years ago I bough damaged 2014 Jetta for my mother from IAAI, and it came with Bridgestone Turanza EL400-02 AS tires. Since they were a bit noisy for a Jetta with poor sound insulation, Jetta got a set of Michelin Energy Saver for summer and Gislaved Euro Frost 5 for winter. I put those almost new (10k miles) Bridgestones on my working horse Passat 4motion, they were ok'ish in summer, since I don't drive aggresive with that car, but when the winter was comming and temps dropped to ~5C (40F), they were slippery on wet already. Like always, I put a dedicated winter tires at the end of october, nothing fancy, just cheap chinese winter tires Nordexx Nivius Snow, because I'm getting rid ot that car in few months, and even those cheap tires were miles better on cold wet asphalt, compared to AS bridgestones.
To spice everything up I can add, that in AutoBild winter tire test those Nordexx tires stopped only in 45,7m from 80kmh to 0, when top winter tires does that in 36-38 meters.
