Metzeler Z6 are the same tire as the Pirelli Stradas, as they roll off the same production line, in the same german factory. I've had 2 sets of Z6s and they do well on the dry, wet and even pushed them pretty hard on the Dragon and surrouding road of NC last year.
8-10k miles out of the rears and 14-17k miles out of a front.
Those with the stradas echo similar mileage. Pilot Roads would yield similar mileage. Conti Road Attacks have a strong following on SVR and those with them love them but haven't tried them yet. However my tire of choice is still the Z6!!!
