Tire Sidewall problems of the 2004 Mazda MAZDA3

Sidewall separation goodyear eagle rsa tire original tire on 2004 Mazda 3 driven 21,400 miles. Previously 2 unexplained flat tires. Taken to the dealer to check tires. No cause found. For the third time, air was leaking from the tire and the sidewall separation with a large deep crack was 3/4 around the tire. When I took it to a goodyear dealer I was told that only the eagle rsa were being replaced on the Nissan's and not the Mazda 3. No further explanation was available. I now have to replace at least one tire and perhaps all four because of this safety hazard.

All 4 eagle rs a p205 goodyear tires on my 2004 Mazda 3 4 door sedan are defective. One tire the sidewall totally cracked and separted and the other 3 tires are beginning to crack and separte. I believe these tires are defective and are a safety hazzard. The goodyear dealer has refused to rectify this situation. I know the tires on the Nissan cars are being replaced for the same defect. However, I was told by the dealer that I would need to replace one tire and the dealer did not check the other 3 tires which when I took my car to another dealer who showed me the separating sidewalls and told me that they need to be replaced. The tire listed as the only option for eagle rsa on your form is p245. These tires in question are p205 so I am not sure how to report this defect.
