My choice for UHP tires,

All can give you at least 40,000km with proper alignment, balancing and rotation. If you sayang your tires, do it every 5000KM, never exceed 10,000km. Maintain a slightly higher pressure for the tires too.

But I can tell you one thing, seems like our Michelin friend quality is slightly drop (used to be the best).....Goodyear quality is unpredictable....and so is Conti.
Thats how it is....
