You need a 4-wheel alignment

Thanks Scott, and others. I appreciate the input from those with experience with tire wear and alignment.
I wish I had kept the alignment printout to compare specs. I lowered the car, approx 30mm last winter before putting on these tires and realigning. I had asked for to be at the mildest end of the spec spectrum. With the lowering, negative camber could not quite be brought into spec, but was close to higher negative camber end of the spectrum. Toe was set to as close to zero end of spectrum as they could get (very mildly toed in), and well within spec. Since I have been trying to learn a little about alignment specs and 996 suspension to try to understand how it all works.
From what I've read, it would appear that 996 multilink rear suspension tends to toe out on compression, which seems to make sense looking at the arc of the links with the wheels off. This got me wondering if having almost zero toe in at static, might actually be creating a situation of excessive toe out under load, or accelerating? There is a very good chance I'm way off on this, but I throw myself to the collective of much smarter people than me here at Rennlist. Previous to lowering, tires also seemed to wear most heavily on inside edges, although not quite as bad.

Toe-out in compression, in the rear, usually induces oversteer. I doubt that is the way the suspension is designed.
You would do well to have it aligned to spec and have them take a little off the negative camber spec (go more vertical).

It's actually so much different that the same things apply. Slightly more wear on the inboard side of the tire is much more common, and less of an issue, at the rear. Dialing out a slight amount of negative camber will help. Much less change than if this were at the front.

my tire wear isbasically identical to yours, and I got twenty thousand miles out of my Continental all season tires and I just replace them with some Michelin a few weeks ago. I would not be concerned

glad i asked
i agree w scott above - this is kinda normal
if u want less inside edge wear just dial out some rear neg camber, otherwise leave it if the car feels good to you on the move
