    So what you're looking at is actually two different places on my FR steer. Firestones, around 60k on them, front shocks replaced around 90k ago and the truck has had the front end looked a few weeks ago (before this), nothing worn on any suspension component. It was in the shop for a front left wheel bearing and to have my king pins checked.

    If you run your hand along these spots with the tread there is a noticeable dip in the tread. Tire man, over the phone, said it sounds like 'center punch' to him and was quick to say it didn't sound like a broken belt. Of course he's going to blame my suspension so he doesn't have to warranty a tire. I've seen a broken belt in a few tires but it didn't look like this.

    I’d say it’s a blem. Looks like an air bubble got in it during the moulding process. Is it an original (Virgin) tire or a re-tread?

    Virgin, I've got vibration mostly when bobtailing around 55, that's the only problem. I had some vibration in these before and was due for a balance but now not sure what to do.

    I also had strange and hard to explain steer tire distortions until I switched to Michelins.
    I also replaced king pins, springs... almost all suspension elements and did the alignment prior to switching but I believe that with Michelins such things are less likely to happen.

    I agree Joe, I have always run Michelins on this truck before but tried these for a cheaper option. I'm starting to think that's what I got :D.

    Did springs make any difference on your truck? I swear mine just doesn't seem to ride as good as it used to. 850 on it now, front springs original.

    I'm not sure, to be 100% honest, but I was tired of seeing steer tires go bad after 50k miles so I decided to replace freaken everything that had anything to do with the steer axle.
    It cost me all over 6k but it was worth every penny. Here I am 700 000 miles later with only 4th set of Michelins recently bought. They last at least 200 000 miles and then another 150 000 on a trailer.

    Besides what has been mentioned above..

    I've seen worn u joints and carrier bearings cause vibrations that cause funky tire wear.
