Explaining that the effect on the cars' aerodynamic package had been a factor when considering what change to make, Hembery said that it was useful to be able to allow the teams to use some of the data they collected last season.
F1 ringmaster Bernie Ecclestone is the latest addition to a growing line of detractors for this year's tyre, claiming that Pirelli had gone beyond the remit of making the sport more exciting, which it was given after the Canadian Grand Prix
a couple of years ago.
“The tyres are wrong, not what we intended when we asked Pirelli to produce something which did a half race,” Ecclestone told Britain's Daily Express
newspaper, “Pirelli know it and they're doing something about it. We'll go back to last season's type of tyres, which gave us some close racing.”
