That looks more like a split or crack than a cut to me also. Several such splits, especially on the sidewalls, would indicate compound separation, poor storage or maybe extreme over- or under-inflation--not road debris damage, unless you're in the habit of tear-assing through the scrap piles of lightbulb or razor blade factories.
If they're Pirellis, as a Google search will soon indicate, it wouldn't be the first time "separation cracks" appeared in their products.
Good luck with pressing your warranty claim, Bro!
