ellisinA4

Found a huge bump on my tire couple days ago. No damage on the rim (never hit anything on the road). Went to the dealer and said that I want a new tire since it was, obviously, a manufacturer's defect. They told me that they can not do anything and that I have to call Micheline and talk to them about it. They also mentioned that I have no chance to get a new tire.

2000 A4, 15K miles.

Any help will be appreciated.
