In my view it is stupid to specify an SUV on 20-inch wheels that necessitate very low profile tyres that, in turn, makes both the tyres and the rims very vulnerable to damage that could result in a blowout like this. But increasing your vulnerability to damage does not make either the supplying dealer or Audi itself liable for what happened.

They will always be able to claim that the blowout was cause by damage from something lying in the road or a pothole in the road or by kerb damage or damage from speed cushions. If a check on the tyre reveals severe wear to the inner shoulder or the other tyre on the same axle then the culprit was almost inevitably the practice of straddling speed cushions that causes severe unseen abrasion to the inner shoulders of car tyres. Speed cushions should be traversed one wheel over the crown and one wheel on the flat between the cushions.
