Default Camber wear? Odd tire wear I cant put my finger on

I have odd inner shoulder wear that I cant put my finger on. Its only the front tires, and its the inner inch or so of tread. That part of the tire wears faster than any other part.

I do have the Eibach camber bolts (-1.75* claimed) plus the stock camber bolt, which gives me 2.5* negative camber. I dont think thats too much, is it?

Ive done my own alignment with nhluhr's string method, and everything is zero.

Any ideas?

You sure it's not a toe issue? You do a ton of highway driving?

I've got roughly the same up front (-2.4) and a few thousand miles on my Advans with no difference in wear on inner/outer edge...I still have the rubber mold nibbles on the tread still

If your caster is way off can't that force you to correct with the steering and in a sense give yourself a toe angle? (I have no idea on this...just remember reading something on this in passing a long time ago).

I think 2.5 degrees of camber AND lots of highway can certainly cause inner wear that resembles toe out...

Default scrub radius

2.5 degrees is alot of negative camber, you need to increase your scrub radius by increasing your positive toe.

And I think this is going to be the root cause, personally. I may just take the camber bolts back out and swap them in for AutoX/track. For the street, they really are overkill anyway. Besides, Ive gotten to where I can do the alignment in less than an hour, so it wouldnt be a big deal to swap.

Bump. Toe was dead on. Im thinking this is camber wear over 10k miles. Camber bolts are coming out this weekend. Basically, the guy at the shop told me everything REX8 said, and I agree. Besides, it takes me an hour or less to swap them in and out. I think I can handle that.

so I have this issue but I'm not sure it's related...
My steering wheel has always been slightly cocked to the left when driving straight. This was during my first set of tires.
A while back when i got my second set of tires(now currently shopping for my third),
and I had an alignment done. I brought it to SEARS to get it done. The guys there had a heck of a time adjusting the front wheels and even stripped one of the bolts underneath. He did manage to get the steering wheel cocked straight and after test driving it, it was driving straight.

Anyways guy at Sears said to goto Subaru to get bolt replaced. Long story short I got the bolt replaced and even an additional aligment from Subaru courtesy of SEARS.
However after Subaru was finished with it, my steering wheel was back cocked slightly to the left again.

At the time I didn't put two and two together, but now that I'm seeing both my first set of tires and my second set having un-even wear on the edges of the tires I'm thinking....who is aligning my tires correctly? Or what can be done to fix this.

I did religiously rotate my second set about every 3k miles with the exception of the last 6k miles.

so i'm guessing the toe zero check will be done by any wheel alignment center?

This is your problem. Go to a performance oriented place.

2.5* is alot of camber i run 1.7* front with 0 toe and 2.0* in the rear with .10* of positive toe and my tires wear perfectly even. only because i drive my car hard everywere. im a service manager at big brand tires and alignment tech so i always adjust my own alignment. the reason your steering wheel is off is the rack bushings. get some whiteline and that wont happen anymore

Its NOT the camber!

Have you tried checking your tire pressure? I'm still confident its a toe issue but whoever is adjusting it does not know what they are doing.

I cant speak to that much negative camber on a wrx but I am am running -3* on the front of my del sol and -2* on the back. both are set to 0 toe and had no real ill effect on the tires.

keep in mind my tires have a lot more sidewall then my wrx with 17s... food for though.

Anyway I would bet on the toe being the issue.

But the thing is I've been driving with a Subaru alignment job and not Sears. As a result my tires had worn out inner edges and my steering wheel was cocked slightly to the left. Sears's job left me with a straight Steering wheel but tire wear I'm not too sure because it was a week later I took it to subaru to fix the stripped bolt.
