What causes this tire wear

Toe and or camber is either off or set to be very aggressive.
I assume the other tire is the same? If not then a curb strike could have whacked the alignment (does the car pull?), or inner/outer tie rods are worn.
If it's the rear (which this looks like since you are changing oil) probably not the curb strike.
Others will add other possibilities......

Both rears. Yes I checked the fronts and they are not the same. I have new tires delivered from tire rack to be mounted this week. I'll then drive to the shop and have them fix the issue. Thanks for the speedy replies.

After the rears were replaced, I did have it realigned to go from the more aggressive side of the tolerance for camber and toe to the other side of the tolerance, to perhaps get a slightly better wear pattern balance. One would give up some performance handling with this approach.

Toe being off will wear the insides like this very quickly, in my experience its a bigger factor than camber alone.
I.e. you can run aggressive camber with correct toe specs and not get this but normal camber with incorrect toe will kill the tires like this.....

(Don't go by what you see from other brands of cars that have goofy wheel/tire combos and the cars showing massive amounts of camber with the tires obviouly riding on just part of the tire tread.)
Furthermore my expeirence is even with the max. allowed amount of camber rear tire wear is still just fine (I get 20K+ miles) as long as the toe is correct.
Whenever I have my cars alignned I ask for an alignment that is condusive to even rear (and front) tire wear and long tire life *without* compromising the car's handling, road feel, stability, etc.
The tech always delivers and even with my 996 Turbo manage 20K+ miles before the wear reaches the wear bars.
There is some rear toe but it ain't much.

Correct! Toe is the issue. The rear negative toe makes the car 'safer' for hot/inexperienced drivers. Minimal toe requires proper driving but improves dynamics and reduces wear. Negative camber should stay untouched.

The alignment has tolerances. If you don't need aggressive handling, you can have your (talented) alignment guy set the rear on the less aggressive side of the spec.

Good advice from all. I had the same problem and reduced the rear toe. I now get the same inside wear, but that's after 25K plus miles on MPSS tires.
Find a good independent tire shop with a good brake mechanic. Talk about how you drive and discuss your expectations. If the guy is good, he'll make it right.

I have a mildly aggressive alignment which produces wear patterns like this, but not as bad. I try and remember to check often enough to catch it and then have my tire shop flip that tires on on the rims. It costs about $25/corner, but worth it IMHO. I just do it once per set, but that I get about double the wear out of a set of tires, given my alignment settings...

Thanks guys for all the advice / input. I was at my pops house for ribs, that is why I haven't replied to yous. I have a place in Ann Arbor that I take my car. I'll speak to them about what yous have said. Thanks again.

Try taking corners faster to even out the wear :-)
