Tire Bubble problems of the 2003 Lexus SC430

This is an issue involving the apparent failure of three out of four goodyear assemetric tires. First isue was a bubble found on the outside sidewall of the right front tire. Approximately 1 week later the left front tire let loose a thin very long ribbon of rubber from the inside edge of the tread. A few months later the left rear inner sidewall blew out in two places like a bursting bubble. These tires have the same date code and were put on the car at the same time approximately a year and a half prior to the first failure. The tire with the delaminated rubber ribbon was replaced at the time at my cost before I realized there was a pattern here. I have contacted goodyear on numerous occasions and they refused to reimburse me or replace that one or the other defective tires. All old tires are available and in my possession. This complaint is for all three tires. . . Same dot number same date code. . .
