All Road Hazard Warranty from Bridgestone is a ****!!!

Is it possible to place a negative rating on Bridgestone tyres? I don't even want to give them ONE star. They should get NEGATIVE FIVE STARS!!! I bought a pair of Bridgestone Turanza T001 tyres for my Mercedes-Benz C200. 225/50R17 Run-flats. It traveled 950 km, and now sports a huge knob on the sidewall. Needless to be, the so-called "All Road Hazard" only applies to tubeless tyres. To be honest, if I knew this, I would have bought Pirellis or Goodyears. This will definitely be my LAST Turanzas. NEVER again...
