I've owned three 3-series cars with the factory sport suspension. While I put my share of highway miles on my cars (who doesn't in Texas?), I've never been able to get more than about 16K miles out of a set of rear tires because of the suspension settings, mostly the negative camber that is part of sport suspension. The worst I ever got was 8500 miles from some Yokos, and the best was Goodyear Eagle F1 GS-D3s. I'm on Conti DW now, and so is my wife's 128i, so we'll see how that goes - but both our cars have sport suspension. That, and my current 3-series is about to go away in favor of a 2013 335i, equipped with the dreaded runflats. I figure I'll let them wear out and then replace them with non-rft tires.
