    I've got uneven wear on the inner wall of my front passenger tire. I
    had the car aligned back in Dec 06 and the only spec that was out the
    caster 1.5 (spec is 1.8 to 3.8). The dealer mentioned to me that
    caster doesn't affect the wear of the tires. He also said that the
    passenger side (front right) wears out faster. This is new news to
    me, I haven't seen any mention of this before on the boards. I also
    haven't rotated the tires as I wanted to replace the front ones.

    Here is a picture of the passenger (right) front

    Here is a picture of the driver's (left) front.

    Do I need to go somewhere else and get another alignment or is there
    something else going on here?

    I would appreciate any help you could provide.

    Alignment doesn't cause uneven wear. That is caused by something loose/ worn
    in the suspension or unbalanced/ bent tire or rim. Once the uneven wear
    starts even if the problem is fixed it will continue to wear uneven. The
    only fix is replace it.

  3. Regardless of what another poster said, alignment CAN and DOES cause tire
    wear. There are three angles measured - toe, camber, and caster. Of the
    three only caster will not cause abnormal wear (all else being equal). Toe
    and camber cause very definitive tire wear. Toe either too positive or too
    negative (that is the pointed toward each other or away from each other too
    much) will cause wear on either the inside or outside edges but the wear
    will exhibit feathering. Camber misalignment the top of the tire is either
    leaning out or in too much. The wear will be either inside or outside edge
    but the feathering is not present. The fix is to have the alignment measured
    and set to specs after the front end components, that is, ball joints, tie
    rod ends, etc. checked. The other poster was correct in that once abnormal
    wear is well established it will continue to wear in the same fashion
    sometimes. If the worn tire is rotated, in your case to a rear wheel, then
    the wear might stop and a normal wear pattern established....

    News to me, too, I have never heard that before - sounds like bs. If
    anything, I would think the driver's side would wear slightly faster,
    due to always having extra weight on that side of the car - but it
    would be so negligible as to be undetectable, I would think.

    you're getting uneven tire wear from two things:

    1. alignment
    2. uneven driveshaft length.

    bottom line, the dealer is correct.

    Ok so what happens if the before and after on the alignment are within
    specs? I replaced the shock on the right side which is giving me the
    problem last year. Would worn out bushings cause this much of a
    problem? The car only has 69k miles.

    You may recall I had a never ending problem with my inner walls on my
    95 Integra. I gave up on it as no one could find out what the problem
    was. The before and after alignments would be in spec. Not to say this
    would be the case but I want to be prepared just in case this occurs

    Also if this helps here is the printout from last year's alignment:

    Front Left

    Camber -0.3 Range -1.0 to 1.0
    Caster 3.1 Range 1.8 to 3.8
    Toe 0.02 Range -0.08 to 0.08
    Included Angle 7.8
    Turning Angle Diff 7.5

    Front Right

    Camber .2 Range -1.0 to 1.0
    ***Caster 1.5 Range 1.8 to 3.8
    Toe -0.01 Range -0.08 to 0.08
    Included Angle 7.9
    Turning Angle Diff 8.1

    Cross Camber -0.4
    Cross Caster 1.6
    Cross SAI -0.2
    Total Toe 0.01 Specified Range -0.16 to 0.16

    absolutely nothing. "within spec" means it's close enough and that it's
    uneconomic to try making it "perfect". and your numbers are far from
    "perfect". AND you're completely ignoring the other factor i mentioned
    before - uneven driveshaft length. this means you don't have exactly
    the same torque on each wheel, so one wears faster, the shorter one.

    bottom line: if you don't like the cosmetics of very slightly uneven
    wear, as is your case, either buy a vehicle with solid axles or rotate
    your tires. real simple.

    Thanks for your advice. The only out of spec on the front wheel is
    the caster which doesn't effect wear. Surly if you looked at the two
    pictures you can't tell me that the wear on the right tire is normal?
    When I had the alignment done, I had two new tires put on the front of
    the car. The car had 56k miles on it at the time. I then rotated the
    front tires to the rear at 61k miles at which point the rear tires may
    have had 15k miles on them while on the rear of the car. So I've put
    about 8k miles on them while in the front and this is what occurred.
    Please help me understand how a tire on the front of the car with only
    8k miles is normal?

    [usenet etiquette - please don't top post - this thread is really messed

    your biggest problem is the belief that that tire wear is bad!!!!!
    compared with most hondas, it's not at all - you should try a camry.

    as for explanation, despite being "within spec", the geometry is still
    not perfect. add to that little things such as rubber bushings whose
    geometry settles differently under load compared to when stationary on
    an alignment machine, drift caused by following a road crown that is
    cambered, not flat, cornering right faster than left because you don't
    have to stop, toe being designed to be different under load because it
    makes you corner better, using a 2/3 ackerman steering ratio, and the
    other stuff i said before, you will NEVER have perfect tire wear.

    you could try messing with front toe to "compensate" for what you see,
    but i've found that doing so degrades cornering performance.

    again, that tire wear pattern is not excessive or unusual for an
    independent suspension fwd.

  11. Nick,
    Does your car pull to one side? Depending on how far your caster is out of
    specs, it won't cause tire wear but it will cause the car to pull. One of
    the tricks of the alignment trade in such cases is to "adjust" the other
    settings (camber and toe) to compensate for the caster problem and get the
    car to drive straight. Depending on the severity of problem, those
    "adjustments" could be contributing to tire wear. One other question I
    have - What caused the caster to be out of specs? This is usually caused by
    a damaged, bent, or worn suspension component. Has this been addressed?

    The car was involved in two accidents one on each side of the front
    but I think what caused the pulling to the right side was a pothole my
    father or mother hit as I noticed it one day I was driving their car.
    When I had the alignment done last year, the dealer told me that the
    right shock was leaking and was replaced. I did that as I wanted the
    alignment to check out. The inner tread is still wearing, and I don't
    think even after 9k miles on the front it should look like the way it
    is in my pictures. I want to believe what Jim says is true, but I
    still think something is not right especially since the car is pulling
    to the right still. I have it at another dealer today awaiting a
    callback from them. I'll keep you updated.

    Here is an update:

    The dealer found the my inner tie rods had some play and needed to be
    replaced. Also with regards to the caster they had to reposition the
    shims by dropping the cradle and radius arms. I had thought everything
    was ok up until just when I got home. I heard a clank hit the bottom
    of my driver side floor and thought it was a rock or something but it
    sounded like metal hitting metal. Then I was on the highway and the
    passenger side I heard the same thing. Is it possible that the shims
    came loose? I feel and it may just be me but the car is still pulling
    to the right but not as severe as before. I think I'll be calling the
    dealer to have this double checked tomorrow.
