Tire in question: Nankang NS-2. 235/40/R18
Rim: 5Zigen black racing 18 x 9J (So it's stretched but not crazy boso styles, just mildly stretched.
Age: around 5 years, was kept outside on the car but off the ground for 2.5 years. Was bought second hand, I only done about 1,000km's on them.
Story: I was fanging a right corner, then all of a sudden the tire popped (I didn't know that at the time), car went crazy sideways, did correct and didn't die. This tire is located at the rear/left, so it was taking most of the load during that corner.

Is it because my tires are so old and crap that's why it ripped to shreads when I was fanging it, it couldn't handle the MR ness? Or did I hit something damn hard like a Ginsu 2000 that's causing it to rip apart? My rear/right wheel looks perfectly fine, while this one has random cut spots all over the place with the big ones as shown.
Needless to say the sidewalls are totally destroyed from this incident, I'm lucky that the tire didn't get rip off the rim and destroy my rims too.
