anyone having a problems with them? I've got a bubble started in my sidewall, went to the Goodyear dealer and they're going to replace it but on further inspection of all the tires i noticed that I may have 2 more starting on 2 other tires. they were made in mid august of 09 so its not like there old tires. I think I just got a defective set period, because of what I have read, everyone say these are great. I am actually really disappointed in them.
