Annoying as I have the EXACT same symptoms yet I am only at 10kmi - outside Dunlops are bald. I contemplated the Conti's, but do not want to lose runflat/get a spare due to 3rd row seating option.
My next set will be with a fresh alignment to reduce toe to as near as 0 as possible. I'm annoyed because I thought my last 4.8is E53 was bad at tire wear around 15kmi - now I'm only at 10kmi and bald tires - grrrrrr.
