Interesting to listen to Vettel desperately trying to avoid suggesting there's any safety implication in having marginal tyres.
Cos, if he said there was a safety concern, the next question would surely be "Well, in that case, why complain when Pirelli tries to solve the issue?".”
Well that answers obvious - because it's giving one team clear advantage (as shown by Mercedes suddenly showing a spurt of speed since the test). They may need to do a mid-season test with 2013 cars after today but, if so, all teams should be involved in it, not just one.
And most tyres appear to suffer from at least partial delamination if not more after a run. The point is that they cut and delaminate to force pits stops.
Maybe it's time for the FIA to request the strongest tyres as possible from Pirelli and change the regulations so the fuel boxes have to be refilled mid-race instead.
