Pirelli has abandoned its plans to introduce its new tyres to the world of Formula One at the British Grand Prix.
Following heavy criticism from teams, most notably Red Bull and Mercedes, due to the delamination problems seen so far this year, the Italian tyre manufacturer has tweaked the design and was hoping to introduce its new tyres at Silverstone.
This had led to it replacing an innter steel belt with a kevlar one, which was tested for the first time in Montreal last week ahead of the Canadian Grand Prix.
However, while certain teams are unhappy with the tyres, others are more comfortable with the existing design, including Ferrari, Lotus and Force India, and therefore they are reluctant to agree to the race debut of the modified tyre.
And herein lies the problem – apparently, because the delaminations are an aesthetic problem rather a safety one, the switch to the new tyres can only be made if the teams unanimously agree.
Paul Hembery, the head of motorsport for Pirelli, has reportedly said the reason for not debuting the tyre in Britain is because of the weather-interrupted testing in Montreal on Friday.
But it is also obvious that some teams are simply vetoing the change.
“From my point of view,” Ferrari’s Stefano Domenicali is quoted by O Estado de S.Paulo newspaper, “changing the tyres during the season is wrong.”
And after Paul di Resta ran for 57 laps before his first pitstop in Montreal, Force India sporting director Otmar Szafnauer agreed: “We have had no problems with delaminations.
“Why should Pirelli change the tyres if we have shown that everything is ok?” he is quoted by Auto Motor und Sport.
And Spain’s El Pais quoted a F1 team source as suggesting that rivals like Red Bull and Mercedes will have to get used to the current situation.
“Let them change the geometry of the suspension and improve their aerodynamics,” the source said.
