OK, I have a '97 E36 328i with sports package and the Turanzas with a 140 treadwear. I estimate that I have roughly 26k miles on them (I have Blizzaks in the winter) and the rears are starting to show signs of real treadwear on them. Are these guys known for low tread life????? I know tirerack gives them like a 4.4/10 rating on treadlife. I was thinking about going for a set of Dunlop SP9000s that seems to be the rave for wet/dry real world driving. I don't race on a track, just spirited road driving now and then... Obviously I would only use this for non-winter conditions as I have snow tires...
