I had that on my michelins. When i let them down, the uneven wear didn't go away so i guess the steel wires were forced into a certain shape when overinflated from new. I have since read here somewhere that, if overinflated from new, tires may wear in the centre due to incorrect bedding in of the steel wires in the tire. This appears to not happen if they are run at normal pressures for a while (not long i hope) and then overinflated.
When i get my next tires i'll leave them at 35psi for the first week or so. Then i'll go the whole hog on them!
I know we mostly say there is no uneven wear but there may be cases where this is not the case. Anyway, they'd wear unevenly at the reccommended pressures too and that's not considered a problem is it??!!
