I got two tires from wal mart on 1/28/2008. Couple of months later, I found a tire has bump on sidewall. I let walmart inspect it. They said it should be ok. While our family (my wife, 5years and 6 months boy's and me) are on vacation driving from austin tx to yellowstone Wyoming, we stayed over a night in fort collins and my wife drove in the morning on 8/11/2009 to yellowstone. Just passed exit 54 and curved road on HW25 nb, the car was lost its balance and shaken alot with bad small. My wife was so embarrassed and pulled out the car on the side road. If there was any car beside or behind us, we would be in very dangerous situation. I checked the tire and sidewall was blown out which previously has a bump. I called towing company for replacing it with spare one and reported this issue to "good year" (claim # - 1061512). On 8/18, I went walmart where I purchased them and they replaced it with new one. I asked I want to keep incident tire with me but they have to return it because of warranty replacement.
