x2 even if didnt notice unpacking did you not look when you put them on the car? having been a tire jock for a couple years we do premount and post mount on all tires we mounted and anything that didnt look right we told customer and should after that choise theres they use there problem did it even if they where new cause they could have blem so if you mounted put on car and didnt inspect until after the car was run then my opinion is that its your bad and you need to live with it.
