I just checked the build date and the tires where built on August in 2011. I bought them in June 2012. I have used tire dressing on them but probably two or three times. I am going camping tomorrow and won't be back until Monday. I plan on going up to discount tire and having them look at them. If they tell me they are not safe and should be replaced than I will see what I can do to get my money back. I am not going to buy another set of tires from discount ever again. The people they have selling you tires have no idea what they are talking about when it comes to cars.
