I just had bad luck too... 4 brand new tires.
Within 1 week. 2 Screws found in tires. 1 Was not deep and facing the sidewall driver's side. The 2nd..Flat right in the middle rib of the Hankook Evo tire as I hit the on ramp. I needed to get that one patched....Needless to say... I feel cursed...like how does that even happen. Literally perfectly in the center of the tire.
