Hembery: Tyre change not prompted by any one team
Despite complaints from various teams since the season began, Pirelli's Paul Hembery insists that the introduction of a new specification is the company's own decision.
Pirelli's Paul Hembery insists that the planned change of tyre specification that will take effect from next month's Canadian Grand Prix was not prompted by complaints from any particular team.
Despite apparently uttering the throwaway line asking why the teams would want Pirelli to produce rubber 'that favoured Red Bull' in the wake of further complaints after Sunday's Spanish Grand Prix saw the majority of drivers make four stops for fresh tyres, Hembery yesterday [Wednesday] confirmed that a new specification would be in place by the time the circus headed to Montreal in June.
However, the Briton was quick to point out that the change had not been made to satisfy the teams, preferring to explain it away in the name of the show, with Pirelli having appeared to have gone too aggressive in its design policy for 2013.
"In terms of [Red Bull team principal] Christian Horner, I think we've spoken for about five minutes on this subject," Hembery has told Sky Sports News, "It's really a Pirelli decision. We have to look at all the teams and the situation as we see it going forward and that's the basis for the decision.
"You're not going to please everybody and that's a factor. People will point out Lotus and Ferrari and say that, from their point of view, things are okay [as they are at present], but Red Bull have still won two races this year and are leading the championship, so they haven't been doing too badly, even with the current product.
"We have to make a decision based on the data we acquire from all eleven teams. Of course, you may get a team that will prefer an approach more than another, but we try and take, let's say, the most neutral approach to making our decisions so it's best for the majority."
Hembery has revealed that the 'new' will something of a hybrid between this year's specification and the 2012 version favoured by the likes of Red Bull and Mercedes. Last year's model had stiffer sidewalls, which caused its shape to change slightly less under aerodynamic loads than its successor. The change might also help McLaren, which is understood to have struggled with the latest tyre after failing to correctly model its characteristics during the design of its MP4-28.
"We're going to give teams a lot more data tomorrow," Hembery continued, “We're finalising the precise specification [but], really, it's a little bit of a mix of what we've been using this season and some of the structural stuff we had last season, which will help minimise the impact for the teams.
"As you can imagine, there's a lot of work to be done on aerodynamics and tyres can impact on that, with the way they deform, so teams will be keen to have that data ASAP so they can all start working towards Canada.”
