I appreciate all of your comments, gentlemen.

I'm taking the car in on Saturday to the local shop I'd discussed in earlier posts. They're going to look at it free of charge since they mounted the tires and performed the alignment.

What the guy said to me on the phone this afternoon was this:

"350Z's, Crossfires, Corvettes - we see these cars in here everyday and it's not at all unusual to see tread wear that is a little unusual. These cars eat through tires, unfortunately. Bring the car in and ask for me or (another guy) and we'll make sure the tires aren't knife edging too bad, plus we'll throw it up on the rack and see what the alignment looks like at this point, no charge."

While I appreciate their gesture, I'm somewhat put off by the idea that "these cars eat through tires." Fair enough, when you can't rotate the tires I'd expect to see less than ideal life spans, but these tires haven't even had 5k on them yet since mounted - way less than that, actually. I find it extremely difficult to believe this is normal in such a short span of mileage. I'm no tire expert, but that sounds like a cop out to me. I'd believe that if these things had 10k on them, but they don't.

We'll see what they have to say come Saturday, but I suspect they're going to tell me the same thing they told me before: there's nothing wrong with the alignment. If that's the case, I may have to start looking for yet another shop.

Lastly, my BAS/ESP light keeps coming on now. It will go off, then come back on. This has been a problem for some time, and I suspect that it has something to do with the wheels vibrating because of the improper alignment/weird tire wear. When I had the new tires put on, that light disappeared. Now that I'm noticing the wear, the light is back. Coincidence? I find it hard to believe considering what I know about the sensors in the hubs that cause that light to appear.

Thanks again, guys.
