Looks like my alignment is really bad. At about 7400 miles I noticed that my driver rear tire is toast. Scheduled a service appointment for later this month at the factory to get the alignment inspected. Meanwhile have to use factory 19s. It's a shame how poorly the wear on the back tire is. Majority of the tire is fine, but it's riding heavy on the inside edge (specially driver rear). First picture is driver rear, second passenger rear and the other two are front tires.
