The current Motorsport Director of Pirelli, Paul Hembery, has admitted that they are not where they need to be with the 2015 tyres and that they are working to ensure that next year's compounds will force the teams to pit two or three times per race.
Ever since taking over from Bridgestone in 2011, Pirelli have been at the epicenter of a vast amount of criticism from teams and drivers.
There have been a number of high profile occasions where teams or drivers have criticised the Pirelli tyre compounds. Adrian Sutil described the 2013 tyres as the "worst he had ever driven" while Jenson Button called them 'twitchy' and said that they "take away the grip that they have given you."

Of course there were the numerous incidents during the 2013 British Grand Prix, during which there were 7 'tyre failures'.
Pirelli tried numerous times to blame this on a vast amount of different things however it was eventually revealed that the issue was with the design of the tyres, which forced Pirelli to change the structure of the compounds.
Complaints from Pirelli
Paul Hembery has told the media that he feels that part of their problem is that they have zero testing. He has said part of the blame for the tyres not being where they are supposed to is that they have not been doing their job correctly however they have also said that they can't do their job to the standard that they need to without full testing access.
Romain Grosjean has said that he wants to see the Pirelli tyres to return to the way that they were during the 2012 season, when pushing the tyres too hard would force them to fall off the cliff.
Paul Hembery agrees with Grosjean's opinion, however he does not feel that the cliff should be as extreme as is has been in previous years. He feels that a driver should be able to "hit the cliff" and not fall down 10 positions on the last lap.
What this means for next season
Hopefully this will mean that next year we will go back to having two or three stop races, which bring more excitement to the sport.
It could also mean that they are going to being more tyre compounds into the sport, bringing more variation to races, and they could be more suited to the tracks that they are at.
What do you guys think? Should we go back to two or three stops? Or should it stay the way it is?
