Tire Sidewall problems of the 2005 Chevrolet Malibu

On 12/16/14 I purchased a set of 4 new 215/60r/16 95t goodyear viva2 tires from louisville walmart supercenter 175 outer loop louisville, ky 40214 for a 2005 Chevrolet Malibu maxx. On 05/19/2015, with appropriately 1500 miles on the tires. While driving at 50 mph the right rear tire failed due to sidewall separation. Due to low speed and light traffic there was no accident, at highway speed this would not have been the case. No damage to the tire other than sidewall separation was noted by walmart service technician. I was not told until later that the tire was replaced by a goodyear 215/60r/16 95t viva 3 with a different treed pattern(I do not feel this is safe) due to goodyear no longer making the viva 2 due to problems with the tire.

I have a Chevrolet Malibu 2005, the sidewalls of the tires are cracking and I need to replace them. I have only had my vehicle for a year and a half. I have always kept up my services and tire rotations. I have another vehicle 2005 with different tires and never had any problems. My front passenger tire blew out due to the sidewall cracking. I now have to replace all four tires. Due to this problem. I shouldn't have to pay for them, they should be replaced at manufacturer's expense due to all the damages I have recently read up on this problem.

Failure was a sidewall blowout. Cause was a slight curb strike. This 2005 Chevrolet Malibu has 1200 miles. This is the second tire failure, the first one happened at 850 miles.
