Pirelli says the truth?
The blowouts of Sebastian Vettel dominated after the race at Spa, the discussion in the paddock. But there were also other important issues that we clarify in our race analysis.
Pirelli vs. Ferrari - who is right?
After blowouts of Sebastian Vettel on the penultimate lap medial heavy guns were ascended. The German criticized the quality of the Italian rubber with sharp words. The tire supplier countered with criticism of the risky strategy that included a long stint on medium 29 laps. Ferrari team boss Maurizio Arrivabene replied that it was before the race from the Pirelli bearing no sign that the gums do not survive such maturities.
The reactions of the competition were divided into two parts. At Mercedes could see the tactical decision Ferraris not understand and spoke of an unnecessary risk. Force India and Lotus contrast provided support for the strategy. "The tires must endure this distance," said Lotus chief engineer Alan Permane. "For us a one-stop tactic was Plan B. We have not waived because it was dangerous, but because it was slow."
Force India technical director Andy Green remarked that the good lap times Vettel speak before blowouts against excessive wear. There is no rubber is more on the tread, the tires would cool sharply, which is reflected in a lack of grip and a massive waste of time. But this was obviously not the case.
Whether the Pirelli tires have a structural problem, can not be proved true.The wear-theory of the tire manufacturer with which they tried to explain the defect shortly after crossing the finish line, but also stands on shaky ground.Instead of hasty condemnation Ferraris Pirelli could at least have to wait for an investigation of shredded tires.
It has a lot to do with the claim Pirelli is "consistent" and "telling the truth".
That's funny.
