The Formula One tyre supplier explained that, put undue pressure on the wrong sidewall, low tyre pressures, extreme cambers and suffered cuts from Silverstone's high kerbs - especially from The round, following the consequences was tyre failures.
Many teams try-out with "tyre swapping, the tyre mounted with the right-hand tyre on the left-hand side and vice-a-versa. Lop-sided construction of its tyres had not been designed to be used in this way and had put extra stress on the sidewalls where the cuts had appeared. Last year tyre swapping was gain a performance advantage.
This weekend at Germany Pirelli will bring revised rear tyres with a Kevlar belt rather than steel, before it reintroduces its 2012 design construction from the Hungarian Grand Prix onwards. It has also asked the FIA to introduce a new regulation to allow it access to real-time data from the teams regarding pressure, temperature and camber angles.
The statement Pirelli made clarification: "The 2013 tyres do not compromise safety if used in the correct way".
"Pirelli would like to underline that the 2013 tyre range does not compromise driver safety in any way if used in the correct manner, and that it meets all the safety standards requested by the FIA."
"I'd like to re-emphasise the fact that the 2013 range of tyres, used in the correct way, is completely safe," Pirelli motorsport boss Paul Hembery said.
"What happened at Silverstone though has led us to ask for full access to real time tyre data to ensure the correct usage and development of tyres that have the sophistication we were asked to provide and extremely high performance that has lowered lap times by more than two seconds on average. While we wait for a change in the rules, we will introduce tyres that are easier to manage."
"Contrary to the impression that some people have formed, I would like to underline the collaboration and support that we are receiving from the teams, drivers, FIA and FOM. In no way are we intending to create arguments or attack anybody.”
“We have taken our responsibilities upon ourselves as our press release indicates. But not having full control over all the elements that impact on the use of the tyres, we need everybody's contribution. With regard to this, we are receiving the full support of all the parties involved, for which we are very grateful."
