I just thought about this because I need new tires. I 'think' I had brand new tires when I got the car last July @99k. Now have almost 109k and they need to be replaced. Mid-Outside tread is absolutely fine....camber wear on inside of fronts and a little in the rear with other wear in the middle of the tires (Pirelli PZero)
Note: I had blizzak winters on for 1-2k miles during that too..
I'm looking into the new Michelin Pilot Super Sport tires that have a 30k warranty for square set-ups and a 15k mile warranty for staggered set-up's. (see my previous thread in the classifieds if you're nearby and like to help me become a square set up)
How long do your tires last?
