The tyre saga has taken a new twist with the Grand Prix Drivers' Association (GPDA) threatening to boycott the German GP if there is a repeat of the Silverstone blowouts.
The issue of safety in Formula One is back in the headlines after four different drivers suffered left-rear tyre failures during Sunday's British Grand Prix.
Although Pirelli has already confirmed that new Kevlar-belted tyres will be used at this weekend's race at Nurburgring, the GPDA has warned that they won't hesitate to withdraw from the race if there are similar problems.
The GDPA, which represents most drivers on the grid, issued the following statement on Thursday evening: "The drivers of the Grand Prix Drivers' Association wish to express their deepest concerns about the events that took place at Silverstone.
"We trust that the changes made to the tyres will have the desired results and that similar problems will not occur during the German GP weekend.
"We are ready to drive our cars to the limit, as we always do, and as it is expected by our teams, sponsors and fans.
"However, the drivers have decided that, if similar problems should manifest themselves during the German GP, we shall immediately withdraw from the event, as this avoidable problem with the tyres endangers again the lives of drivers, marshals and fans."
Jenson Button, the director of the GPDA, is hopeful that the new tyres will bring an end to the problems.
"We haven't seen an issue with this type of construction. As far as I know, it's very similar to what we had last year, using Kevlar instead of metal in the tyre. We didn't have any issues last year.
"I'm happy that they're able to bring this tyre; three or four days to sort the tyres out and bring a completely different construction is fantastic."
Meanwhile, Red Bull driver Mark Webber said: "Actions speak louder than words and Pirelli has to do something from a safety perspective.
"Performance is one thing but when you have safety involved, you have to find the right way for all of us.
"Silverstone was a very dramatic and extremely unsafe scenario for all of us."
