Well I've been running a 330d estate for 5 years from new. It came with 19" Goodyear runflats. I suffered 5 tyre failures in the first 20000 miles, bulges in side wall and on one occasion a cracked wheel, and two partial separations of tread from sidewall leaving the car undrivable. Because these happened individually I kept replacing the damaged tyre. I can't comment on wear as I never had a tyre last beyond about 5mm tread depth. Its the first car I've owned where I check the tyre pressures every time I fill up I got so paranoid. In the end I threw the whole lot away and replaced them with conventional tyres since when I have had only one puncture from a screw, unfortunately too close to the sidewall to be repaired and the car's ride and handling is transformed. I bought a space saver with bag and jack etc which I put in the car for longer trips although it does take up boot space. It's my last BMW unless they reintroduce a spare wheel and conventional tyre option.
