I have used 3 sets of Pirelli P-Zero Nero M&S on this BMW because of their UTQG treadwear rating and have been happy with them, but I put a set of the Continental ExtremeContact DW on my Porsche and fell in love with their performance. I was skeptical of the all season version DWS but thought I'd try them because of the high treadwear, the ability to go into cold climates, AND the performance of the DW version. Very impressed after 4000 miles. The grip is excellent (haven't been able to squeal them on a hard start from stop) and no squeal on hard corners. The ride is smooth and quiet. We had a week of heavy rain recently and I pushed the tires to see how they would perform. The grip was amazing on the wet roads. No hydroplaning at all and breaking was the same as on dry roads. Turning was done with confidence in the rain once I tested them to make sure they would stick. After they were tested I took passengers out and they were freaking out that I was driving like it was dry. Only 2 real complaints: 1) steering response is slow, MUCH slower than my DW version on the Porsche and slower than my Pirellis. This isn't as big of an issue as you learn to adjust your driving style to compensate and most of my driving is now on longer straight roads. Noise and comfort are bigger factors now and they perform great. 2) Don't like the tread design look, but if you want to run in snow you'll have to have a pattern that will work in them. I liked them so much, I put a set on my wife's 3 series convertible. She's more interested in comfort, but I use her car occasionally to have some fun. Can't speak for snow traction yet, nor mileage, but the performance for the price is outstanding.
