Continental SCR both front tyre defect

[wslee]

My 10,000KM 10 months old 2 front continental SCR run flat tyres appear with lots of hole, chip/bits came off and crack around the edge of the tyres tread. I ask my dealer service advisor this morning when I sent my car for a warranty repair; they told me this is a common issue for continental tyres on front wheels. He suggests me to change my tyres to Michelin or Bridgestone for a better quality product.
Its doesn't seem right to me that I should change the tyres with my own cost due to the product common problem. I have called Continental Australia, they said they will arrange a local authorize tyres shop to contact me to have a look on the issue.
Does anyone have a similar issue or success claim from Continental ?
Thanks.
