    While rotating the tires, I found that my left rear has 19 bumps, arranged more or less evenly spaced around the tire. Another way to put it would be that there are 19 flat spots on the inside edge of the tread. What does this mean? Some suspension part wearing out? What should I look for?

    I'd guess balance or alignment or the possibility of both.

    How many mines on your MINI? How often do you rotate the tires?

    Shocks....how many miles on the shocks...that could also be the culprit.

    x2 on needing shocks, especially at 93k.

    With that, i do have some "low" mileage sport suspension shock/sturts. That is, if you are not wanting to go full aftermarket with them.

    My shocks have 96K on them. I've been waiting for them to carp out, but so far they have not.:confused5: There is a set of very low mile oem shocks & struts in my garage waiting their turn on my MINI.

    Crashton: Actually, just over 100K. I haven't updated my sig lately.
    Chkmini: These are the original shocks.
    Scottinbend: For a problem on the rear?

    Also, if the problem is only one rear tire, does it follow that all four shocks, assuming they are the culprit are gone? Could I just do rears and then watch the tire wear?

    Yes rear toe.

    And best to do all 4 dampers so the handling isn't affected adversely.

    If you are going to do shock 4 is the way to go as Scott said. If it was mine I'd have the alignment checked first & go from there.

    Sorry I missed the mileage in your sig.

    I wouldn't start replacing dampers until you rule out the cheaper options (balance, alignment, etc) unless you figure it's time to do that anyway. I'd like to see a pic, still trying to interpret your wording about the tire damage. Have you been feeling any vibration when driving?

    Sounds like he is describing feathering of the tire.

    Some pictures would help quite a bit.

    Being this is only on one tire I'd be suspect of the alignment.

    I know, but I don't like to assume, esp. when there's more than one possible cause and potential fix. I'm sure it's not the tire itself but I keep going back to the word "bumps" in the title...conjuring up thoughts of broken belts, etc.

    Anyway, I know there's sometimes no way to zero in on a problem without paying for one fix after another until one of them works, but I tend to start with the cheaper options and work my way up. In other words, I probably wouldn't start with new shocks...unless I was ready to replace them anyway.

    I would assume a balance issue first but since there are so many bumps/voids and they're all on one side of only one tire I suspect it's an alignment problem.

    I found the How to Read Tire Wear thing, too. Definitely looks like "cupping", at least of the choices given. They are just spaced out a lot more. Hard to see, but

    My old BMW had issues like that on the right front tire when I bought the car. The shock was so bad it was leaking fluid. At your mileage you're probably due for new shocks anyways.

    The previous owner of my car didn't address the problem for about 20,000 miles. The bad shock and tire vibration wore out the tie rod ball joints, control arm ball joints, endlinks, and motor mounts on that side. One tire was almost bald and the other three had 50% tread left.
