This was a reply to another tire thread so I'll just paste it over here.
I don't know about the extrem contact (I think that is right) but I was so pissed with the crappy stock Conti's I will never buy another set of anything they make. In my opinion buy Pirelli and you can't go wrong. I have the Pzero Nero M/S all season on my car and they kick the stock conti's ass, I may be starting something here but I would venture to say that the Pzero Nero M/S which is a all season tire is better than Conti's summer only performance tire. I am kind of going out on a limb here since I have never tried the extrem contact conti's but I don't see how tires could get much better than the Pzero Nero. If the Pzero Nero M/S is not better I am sure the Pzero Nero summer perfomance tire is better. I'll look them up and post the results latter.
As I thought, according to Tire Rack the Pirelli's rock.
