I had Conti Extreme Contact DW's on my old 530i and they only lasted ~15k miles which I thought was total crap.
I thought it was just me but... maybe not? I had my alignment checked every 3 months (bought an alignment package that was unlimited alignment) and rotated them regularly. Pressure was good and they had Nitro in them.
Never drove it that hard, stock non-sport suspension. Tires just didn't last worth a crap.
EDIT: I should also mention they were supposedly the 'old' version of the tire with the softer side walls.
