I've got about 10,000 on a set of RoadAttacks. I just got home from a 4,400 mile trip in temps from 60 to 108. The rear is now squared off and has concave wear patterns on both sides of the flat center that appeared after a day of high speed sweepers through PA, VA, and WV. They don't have the wet traction I got on the last set of Bridgestones, and after this trip the rear is not looking good. The front looks GREAT, go figure? Milage however, was very good and with milder temps and slightly less speed, these may have lasted 15k+.
