So, I got the Pirelli Scorpion Zero A/S, and I am happy with them. They are comfortable and quiet. I don't notice any more road noise than the SportContact 6s. I did notice that the old front tires would skip when I turned out of the driveway and in a few other situations. I thought there was something wrong with my suspension at first, lol. Looking back on it, that mostly happened on very cold days with temps in the 20s and 30s.
@Tulipo's comment made me realize what was probably going on with those summer tires. I'm not having that issue now, for sure.
I've never run separate summer and winter tires, but then I never had the instant torque that electric cars give you. I've run all seasons on my cars forever. I had an E39 M5, which was RWD, and I never felt like the A/S didn't have enough grip. I'm still trying to see how much of a compromise I've made going to All Seasons vs Summer tires, but I do think it was the right call for now, especially with the weather turning here in the NOVA/DC area.
If it turns out to be too big of a difference and if I can figure out the storage space issue, I might look into getting a separate set of winter and summer wheels and tires at some point.
I'll try to update my impressions as things develop.
@Tulipo I'm in Fairfax, right next to Centreville. If you are curious about how the Pirellis sound/feel, I'd be happy to meet up.
Thanks again, everyone.
