    Take a look at the pic below:

    Look at the inside edge. It's depth is like new, while the outside edge is much shallower. I'm running -2.0 degrees of camber on this tire. How's the outside edge worn more than the inside?? I would think it'd be the opposite, having the inside worn more than the outside. Is this just a result of my driving style. These are daily driven as well.
    Anybody got any idea's??

    Forgot to mention that it is like this on both fronts.

    The Toe setting is supposed to be at 0. Maybe that's the problem, hmmm
    Would the toe setting cause this kind of wear??

    with 2deg -camber the toe would not make that much diff. Probly waer in the center if toe was in. How often do you track it and what PSI do u run

    not tracked at all, just mountain runs and spirited driving. PSI is set to 40.
    I guess I should measure the diff. between the inside/outside edges

    yikes, spirited driving or not you might wanna rotate your tires more often. i don't think it should be doing that with that much camber @ 40psi. the toe would have to be something stupid to do anything close to that kind of a biased wear.

    do you hug corners a lot or track wide arcs?

    Well, I rotate them every 3K miles, basically every time I change oil.
    I do appreciate a good twisty road and the cold weather has only helped my appreciation. :wiggle:


    Maybe it's just time to get back in for an alignment and make sure that everything's still set fine. I do think that I may have a bad wheel bearing. Haven't had a chance to check it yet, uuggghhh, I hope that I'm wrong.

    Uneven tire wear almost always equals something is out of wack with the alignment. I got mine done in may, but the last few months it's felt funky and my victoracers were wearing unevenly. Took it to GT and my alignment had completely slipped out (I had no front negative camber) over a six month period. I've been told it's best to get car aligned often if you drive your car hard often. While I believe my alignment slipped do autoxing my car just about every weekend, GT refused to let me pay for my re-alignment two weeks ago.

    I agree with Meredith..Unusual tire wear indicates that something is wrong with your alignment..when was the last time you had an alignment?

    every 3k is awesome, yeah definately check the alignment.

    Last tire alignment was in July. I certainly haven't hit anything (potholes, alligators,etc...)
    but yeah, I think it's time to get see the guys at GT. Not that it's a bad thing.
    Thanks for the help guys (and girls) ;)

    OK, got re-aligned today. Feels like a brand new car.
    Big props to Gran Turismo, again. Definately found the problem
    with the tire wear. No explanation as to settings changing though.
    It had been almost 10K miles since my last alignment.
    ** SO amazing what a freaking alignment will do for a car **

    Pre-alignment specs:
    L R
    Front
    Camber -1.8 -1.2 <-- how'd that happen
    Toe .19 .29 <-- how'd THAT happen
    Caster 4.6 4.4

    Rear
    Camber -1.9 -2.1
    Toe 0 0

    Post-alignment specs:
    L R
    Front
    Camber -2.0 -2.0
    Toe 0 0
    Caster 4.6 4.4

    Rear

    Camber -1.9 -2.1
    Toe -.02 -.04
