    You need an alignment. Camber does cause uneven wear but the speed at which you're blowing through them suggest toe is significantly out of alignment. Is your car stock?

    I replaced my MPSS at 35,000 miles and they still had a lot of wear left until they were at the marks.

    Agreed on the observations (not the troll speculation) as this seems like a car with an effed up alignment.

    Hard to imagine camber and- more likely- toe which is that far out of wack where it otherwise behaves OK. Could be a perfect storm of issues here too: tire pressures, alignment, driving style, road surfaces, etc.

    At a minimum, sounds like we're all clear this ain't normal. ;-) Get it on an alignment rack pronto.

    Go back to whomever did the install and alignment. Something isn't right since your wear is excessive and it isn't within spec, have a discussion about getting that tire replaced due to the work done possibly caused the issue. Do you have any kind of road hazard? Last note, have you by chance ran over anything that could've knock anything out of whack? My car came with Cup 2s and I sold them off with 23 miles on them since those tires picked up everything from the local roads, switched over to MPSS for a few Ks and the pre-ship alignment checked/adjusted (the backend was a bit off) since then no issues, then I went to PS4s and still have yet to have any wear issues. I still have my MPSS mounted and they're at 90% tread.

    Something similar to this has happened to me after a track weekend on Cup2's. I was running -2.5 camber at the front and very little toe-out and the inside tread of the front tires was worn out completely. Also, although the outside did not have that much wear it developed scars - whole chunks of the tires completely removed - possibly related to a) under-inflation and b) a couple of incidents where I gave it more steering angle than I should have while the car was pushing for the gravel (this happened rarely). Attached images of one of the fronts which was swapped to the rear at that point.

    You have too much toe in, most likely positive numbers with that kind of wear (Should be -0.10 in the front, -0.15 in the rear). With the alignment that bad, I'm surprised you can't feel it while driving. It will be harder to start a turn, and will fight to pull back straight the whole time.

    You talking about me / my pictures?
    If you are, I have negative toe (toe out) in front, -0.1 and turn in is excellent.

    No, the OP.

    My guess is the car has been hit or smacked a curb by the previous owner and repaired. Likely has a bent control arm / cracked bushing / joint with excessive play giving the car a weird dynamic alignment.
