Well I pulled the trigger and went with Pirelli Cinturato P7 All Season Plus. The customer ratings are quite good, with 100% of purchasers saying they would definitely buy them again. That's high praise. My only concern about them is their wet traction appears to be not quite as good as other tires in the class. In exchange, they have the best ratings for noise and fuel economy (LRR), and snow traction. I still have my dedicated snow tires, but I may try these tires this winter. Let's hope these tires can deal with the demands of the P85D. They aren't high-performance tires; they are grand touring. We'll find out soon enough if I made a mistake!
Thanks to everyone for their opinions, recommendations, etc. If anyone else is shopping right now, Pirelli has a $60 mail-in rebate that expires TODAY (7/6).
