If your tyre delaminated which sounds like it did they have had a bad reputation in the past and been sued in America because of it .

From what I can tell faulty tyres delaminate at speed causing panel damage and or accidents but you would think their manufacturing process and quality control would have improved, I don't buy this brand purely because of this problem they had in America.
It should also be noted that the tyres in question did not like the hotter Climates or lower air pressure .
