Thanks for the reply! Tire pressure is pretty normal for my stock size tires (255/45-18) Max psi I believe is 50 lbs. All 4 tires are right at about 37-38. So I don't think its excessive tire pressure. But no I did not have it aligned after being lowered. My F30 was lowered about 2 mos ago, and I purchased new tires about a week after that.High tire pressure will wear out the center. Did you have it aligned after lowering it?
