Pirelli will be more cautious with camber guidelines for Monza

The Italian firm's rubber was at the centre of discussions during the build-up to Sunday's race over concerns about the Red Bulls blistering tyres in qualifying.

Pirelli and the FIA stood firm following requests from the world championship-leading team to allow it to change its tyres before the start of the race.

Red Bull went on to take a one-two with Sebastian Vettel and Mark Webber in the race at Spa, but its chief technical officer Adrian Newey described the race as one of the scariest he has ever been involved in.

"Well we will be more conservative [with our recommendations], particularly for somewhere like Monza," he said. "You would have to look back at it and say we were confident with the structure of the tyre, to be honest. We knew that the structure of the tyre was extremely strong, and that was proven to be. There weren't any issues at all.

"Graining and blistering are aspects of compound performance in motor racing. It is not exactly a new phenomenon, but there are limits. And ordinarily in free practice, when you see something like this, teams would change their geometry and you would not go into a race in that situation, so it was a combination of circumstance in reality."

Hembery admitted some surprise that teams struggling with blistering opted to continue running the soft tyre, rather than go for the more durable - albeit less competitive - medium compound tyre.

"If you look at the medium tyre, you don't get any blistering, it has higher heat resistance," he said. "What we had hoped here, if somebody was in difficulty, that they would have run the race on the prime tyre that would have run without any issues whatsoever. However, everybody went for performance and that was disappointing."

He added: "I guess what you ultimately hope would happen was that people would see such a phenomenon, you would switch to a product that is not demonstrating such a thing. That is something we need to think about. Performance counts a lot in F1 and it appears people are willing to compromise in order to get that performance."
