Following the sight of four left-rear tyres failing at high speed in the race at Silverstone, it is understood that FIA President Jean Todt has summoned F1's tyre manufacturer to appear at a meeting with team bosses and other relevant parties at the Nurburgring on Wednesday.
"It's in front of what used to be called the Sporting Working Group, actually now called the Sporting Committee," Sky Sports F1's Ted Kravitz reported.
"It will be at the Nurburgring in the paddock and it usually consists of the team managers and anybody else who wants to come from every team. As we understand it, Jean Todt wants Pirelli's attendance at that.
"We don't know if Jean Todt is going to be there, Charlie Whiting chairs it so he's certainly going to be there, so this is just more pressure on Pirelli.
"We have back-to-back races so they're not going to change the construction of the tyres before the Nurburgring, just more pressure on them to make sure the tyres they bring to Germany don't fail in the way that they failed here today."
Pirelli confirmed in the immediate aftermath of Sunday's race that they had launched an investigation into the repeat failures, calling the matter their "top priority".
However, while Pirelli's motorsport chief Paul Hembery suggested the problems represented a "new" issue for the tyre firm, he refused to speculate on their cause before in-house analysis had been completed.
"Obviously today wasn't foreseen - we've seen something new, a different type of problem," he told reporters.
"We're currently performing our analysis. We've got to go away and understand what's happened. When we've got the facts we can understand what's happened and get to the core of the issue. We take these things seriously and when we have the answers we'll let you know."
However, Hembery ruled out the production changes Pirelli had made to the tyres for Silverstone as having had any affect on the failures.
"However, we can exclude that the new bonding process, which we introduced at this race, is at cause for the tyre failures we have seen today," he added.
And when asked by Kravitz if in light of Sunday's incidents Pirelli would be forced to revert to their original plan and change the 2013 rear compounds for safety reasons, Hembery simply replied: "We need to analyse the data and see what has happened."
Mercedes driver Lewis Hamilton had been the first driver to suffer the same left-rear failure in Sunday's race, with repeat issues soon following on Felipe Massa and Jean-Eric Vergne's respective cars.
The Brackley team's controversial Barcelona test last month had been in part conducted, according to the team's defence in last week's Tribunal hearing, to help Pirelli improve the safety of their tyres and team boss Ross Brawn has declared that F1 now has to "have a serious look" at the ongoing problems.
"We will have to look into it," Brawn told Sky Sports F1 after seeing his other driver Nico Rosberg win the race.
"I don't want to comment until we get all the facts, but it is something we will have to have a serious look at.
"Obviously we are at the centre of it following our Barcelona test, but you can see why we were concerned and wanted to do the work. We will have a proper look at it and see what we need to address."
Pirelli statement in full
'There were a number of rear-left tyre failures during the race, which affected Mercedes driver Lewis Hamilton, Felipe Massa (Ferrari), Jean-Eric Vergne (Toro Rosso) and Sergio Perez (McLaren). Pirelli engineers will investigate closely the cause of the failures ahead of next week's German Grand Prix.
'Pirelli's motorsport director Paul Hembery said: "There have obviously been some issues with rear-left tyre failures which we have not seen before. We are taking the situation very seriously and we are currently investigating all tyres to determine the cause as soon as possible, ahead of the next Grand Prix in Germany. At the moment, we can't really say much more until we have fully investigated and analysed all of these incidents, which is our top priority.
'"However, we can exclude that the new bonding process, which we introduced at this race, is at cause for the tyre failures we have seen today. There might be some aspect to this circuit that impacts specifically on the latest version of our 2013 specification tyres but at this point we do not want to speculate but will now put together all the evidence to find out what happened and then take appropriate next steps should these be required".'
