Pirelli has confirmed that changes are to be made to the tyres that will be used in the German Grand Prix this weekend at the Nurburging following a detailed investigation into the cause of the issues encountered in Sunday's British Grand Prix.

In its investigation - full details of which can be found by clicking HERE - the Italian firm claimed that a variety of factors had combined to lead to the blowouts suffered by Lewis Hamilton, Felipe Massa, Jean-Eric Vergne and Sergio Perez.

In a long and detailed statement released to the press, Pirelli claimed that teams had taken the decision to mount rear tyres on the wrong side of the car - a move that placed undue pressure on the wrong side of the tyre given they are designed to run on a specific side of the car - and had also run low tyre pressures and high amounts of camber.

The tyre company also suggested that the kerbs at Silverstone had played a part in the failures, but denied that some of the delamination issues encountered earlier in the year had been a factor.

Despite insisting that its 2013 rubber is safe when used 'in the correct manner', Pirelli has confirmed that it will provide teams with the Kevlar belted tyres that were tested in Canada for the German race.

With the new rear tyres continuing to feature an asymmetric design, teams will be forbidden from swapping the right and left tyres around and will be informed of limits on what camber settings and tyre pressures should be used.

Pirelli will then work to provide a range of symmetrical tyres for the Hungarian Grand Prix onwards which will combine the construction of the 2012 tyres with the compounds being used this season.

These tyres will be tested during the three-day test at Silverstone later this month which was originally supposed to be the annual Young Driver Test.

"What happened at Silverstone was completely unexpected and it was the first time that anything like this has ever occurred in more than a century of Pirelli in motorsport," Pirelli motorsport boss Paul Hembery said. "These incidents, which have upset us greatly, have stressed the urgency of the changes that we already suggested - which will be introduced during for free practice in Germany on Friday.

"We would like to acknowledge the willingness of the FIA, FOM teams, and drivers to act quickly to find an immediate solution to the problem. In particular, the adoption of winter tests, arranged with the FIA, that are more suitable for tyre development and the possibility of carrying out in-season testing will contribute to the realisation of tyres with increasingly improved standards of safety and performance.

"I'd like to re-emphasise the fact that the 2013 range of tyres, used in the correct way, is completely safe. 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."
