Apparently there were two right rear tyre failures, Vettel and Alonso. The drivers aren't happy. Webber has said .....we want answers and debris isn't one of them. Sutil has said he wants a signature from the FIA saying there will be no tyre issues, otherwise he won't race.
Can you blame them? Fu**ing Pirelli tyres which can't even sustain some debris/curbing and getting flats with less than 20 laps of running, I'd be pretty concerned myself. At least these guys got these punctures in Practice, what if we see another 4-5 blow outs in the race from WDC contenders, Pirelli will call that "debris" again?
Ridiculous to blame it on debris, building tyres which lose grip is one thing, but tyres which can get flats so easily due to normal external circumstances such as track characteristics is really pushing the envelope. Bloody Pirelli tyres could seriously screw with the Championships since drivers will be practically gambling and hoping their tyres don't get affected and also gambling with their lives, this is a high speed circuit.
