On the Spec5 Kia was gracious enough to endow our cars with Performance All season tires. I think they were mistaken when they did this. I realize that most people would much rather have all seasons than just summer but I expected them to last quite a lot longer than they did. I have about 3000 miles left on the stock set that came with my car. I have had some problems with them getting low as well. I don't plan on replacing them with the same tires. They are too expensive considering the "performance" and amount of tread life you really get. I plan on putting Hancook RS-212's or Falken's in the stock size. I don't drive where it's cold enough to need an all season tire so what's the point? I did one autocross and a couple of 1/4 mile runs and then normal driving. I have 17,000+ miles on them.
