I just purchased a set of Goodyear Eagle GPS tires for my Integra, I got a discount on them, however when I went to install them I noticed they were shipped in July of 1999! I guess the tire were sitting a warehouse somewhere. I have noticed that a lot of discussion has been about having a "best before date" on tires. Should I return these tires and get something else, ( I have not installed them). Do I worry about them being so old? Thanks for the help.
