Tire wear/alignment ?

[ishredNH]

I had a flat on Friday. I took the tire off to swap to the spare and noticed a really odd wear pattern. The inner part of the right rear was completely worn. That night i went home and swapped to my winters. As I took each tire off it was apparent that all 4 had significant inner tire wear. The tires have 20k+ miles on them and are pretty much junk (the car has 28k). They have been rotated/aligned on schedule so that isn't the issue. I did some research and judging from the wear pattern it looks like either A. I have bent/worn suspension parts on all 4 wheels or B. The alignment is way off. I haven't hit a single pothole since my last alignment in May. For those of you knowledgable about this kind of stuff what do you think? I had belknap subaru do the alignment and the car has been back 3-4 with another rotation mid summer. The sketchy part is I had the car there last week up on the lift and they didnt even mention a tire wear issue to me. As the pictures below will show they are unevenly worn pretty bad. Last time i was there they said the tread was getting low which i was aware of. Is It possible they could have completely botched the alignment? I'm going there in a few hours to show them. Thoughts? Comments? Opinions?

To much static camber (can exaggerates the dynamic when you start of statically negative.) This can happen on the fronts from caster and turning, but it happening on all 4's is odd.

Toe adjustment way out?

i have seen that happen on WRXs with factory spec alignments, a friend of mine had it fixed when he had an auto-x spec alignment put on it. now they wear incredibly even

btw what tires were those?

just noticed my fronts have the same wear on them. It actually makes a nice 90 degree angle on the shoulder of the tire. Funny, cause i had an alignment done last winter at exeter subaru. Guess it's time for another...

we live in a great area to ruin alignment settings. good old potholes, etc. also remember your alignment is set while the car is static and obviously while the car is in motion the suspensions alignment is constantly changing(dynamic). alot of tire wear is up to you and your driving habits, but you should have your alignment adjusted every 6 months IMO for our "neck of the woods".
