Number one: when Sears sends that tire back, MAST (The Company that owns BFG) won't give them a DIME if the tread wear is like you say. Period. So be grateful you're getting anything at all. Seriously.
Number two: Both Jerome and I, as well as SmithSR worked (or still do) in the tire business. We know that what you're describing IS NOT A DEFECT. Tread wear issues aren't caused by defects (unless the MFR miss-compounded the entire tire, which I highly, highly doubt). It's premature tread wear that can be caused (most notably by what you're describing) by over inflation and other problems. So don't accuse him of "not knowing his stuff”. I assure you, he does.
Keep in mind; most gauges are not accurate, even in tire shops. Buy a good one, with a bleed valve and check the tire in the morning, on say, every Sunday. That's the best way to go: once a week. I've seen gauges off by 3psi or more (on the low side)...which could be your problem, you -think- they're at 29, and they may be at 32.
Number three: you are correct the traction T/A comes with 9/32" in the middle by design. Not of any significance, IMO, given your situation of massive center wear.
Also, check your alignment, if you are not running enough negative camber (in spec), you'll be riding exclusively on that centerline of the tire all the time, which would compound and over inflation issue.
Be happy. Most manufacturers will not adjust a tire with any 'wear patterns' in them at all, because in 90% of the cases there was a miss-use or other issue at the heart of it.
Keep something in mind, when a tire manufacturer decides to put a "tread wear" warranty on a tire, they do it by statistical analysis. IE, they look at the distribution of estimated mileage on a certain tire, and say "ok, 95% of these went 60k", we'll put the mileage warranty there, that way we can estimate only 5% will come back with claims...they do this under the assumption (which is a poor one), that the tires will be properly inflated, aligned, and rotated throughout their life and will see "normal service", IE no racing, auto crossing, etc...
I would go and get a good air gauge (race wholesale sells some nice ones between 30-50 dollars) and check your tires yourself, and not trust a gauge that gets beat around all day in a tire shop. I know what happens to those gauges, and I never trusted them while working there. I bought my own.
Good luck. Overall, if you're so sure it's "the tires fault" as the industry people hear so often, you can always buy another brand/type.
