Red Bull, Pirelli, 2011Pirelli motorsport director Paul Hembery insists his company will be more cautious with its recommended camber guidelines for future races following the Belgian Grand Prix tire controversy.

The Italian firm's rubber was at the centre of discussions in the build up to Sunday's race over concerns about the Red Bulls blistering tires in qualifying. Pirelli and the FIA stood firm following requests from the team to allow it to change its tires before the start of the race. Red Bull went on to take a 1-2 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 tire, to be honest. We knew that the structure of the tire 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 pursuing running the soft tire, rather than go for the more durable – albeit less competitive – medium-compound tire.

"If you look at the medium tire, 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 tire 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."
