X6: Got lousy 3k Miles from new Bridgestone Dueler H/P Sport RFT tires - Any ideas?

[zenandnow]

Hey all,

I have a 2010 X6 5.0 xdrive with about 25k miles. I had all four tires replaced at a BMW Service Center in late April with brand new Dueler H/P Sport RFTs, and have put about 3k miles on the car in the 3 months since.

I was driving in the rain the other day and could hardly keep the car on the road so I pulled over to have a look at the tires and couldn't believe it... the front tires still look almost brand new but the rear tires are right down to the wear bars. They're practically bald after 3k miles of highway driving.

I know these are performance tires and that the fronts tend to have a longer life, but I've gotten at least 10-12 k miles out of the rears in the past.

I have an appointment to bring it back in to the dealer who sold me the tires but I thought I'd see if anyone has an idea about how this could happen. I'm guessing that the tires are defective or there was a problem with the installation because I can't imagine what I could have done to wear them out so quickly and unevenly. My driving style certainly hasn't changed and I've had no tire pressure warnings or anything of the sort since installation.

Any thoughts would be greatly appreciated.
