Direzza are fail tires? You have got to be kidding me here, seriously.
Have you ever used them personally?
I've used the Direzza Z1 Star Spec and trust me they were one of the best tires I've used on my car so far in the 195/55R15 size. Even read the reviews online and compare the ratings to other tires of it's class and you'll have a slight idea.
They have amazing traction and are famous among the Autocross family.
Whoever told you the Direzza are fail tires, I'd LOVE to hear some facts from them.
But yeah, when you install the Direzza Z1 and expect them to have the smoothest ride and comfort levels, then they aren't a good choice, these are really good budget summer performance tires.
Michelin Pilot Sport are very good tires as well, they even come as factory equipment on many BMW's.
