From what I understand and have seen you'll be lucky to get 4000k (2500miles) out of a rear tire.
It seems that the belt tensioner does such a good job of keeping the slack out of the driveline that there is always torque being applied to the wheel, even when coasting and decelerating, hence greater tire wear.
