If you drive less and have separate summer/winter tires, it has the odd side-effect of making long-wear tires not worthwhile, as the life of the tread depth will exceed the life of the rubber due to age.
I drive about 3.5k miles a year, the OEM tires would have given me 70k miles but I would have never got there. the michelin pilot sport 4s where $5 more per tire and would survive just about 7 years (i'm planning 3-4 with the occasional track day). the tradeoff was DEFINITELY worth it, but now i'm deathly afraid of potholes and road hazards lol!
(after 1000 miles on the MP4S you're already more than 1/16th worn and would need to replace the entire set to keep the AWD system happy)
