Paul Hembery, Pirelli's Motorsport Director, says the Italian tyre manufacturer will attempt to bring back higher degradation levels next year after Grands Prix in the final phase of the 2012 season became largely single pit-stop exercises.
A dramatic start to the 2012 campaign saw seven different winners from the first seven races, with the unpredictability being heavily attributed to Pirelli's new rubber. However, as the season wore on and data was gathered at various circuits, Hembery said teams were able to understand the differences and 'dominate the situation'.
When asked by GPUpdate.net if increased degradation and wider operating windows are expected in 2013, Hembery replied: "That’s pretty much it. There’s a more rapid warm-up and more temperature going into the tyres, basically because they are working harder and because we’ll have a bigger footprint in cornering.
"With the changes we’re making to the compounds we’re trying to bring back some degradation levels, because quite frankly at the end of the season we were in negative degradation and maybe not where we were asked to be. We were maybe repeating some races from the past where we were down to one pit-stop and I’m not going to say it was too easy, but teams were dominating the situation."
Hembery also discussed the development Hard tyre rolled out in Brazil, with teams and drivers attempting to understand the tweaks in store for the 2013 campaign.
"It was only a limited amount of driving and it was on a green track as well, but overall it pretty much matches what we saw in our own testing," he added. "They didn’t try any of the new compounds, it was the existing Hard tyre that they used, but it showed us that the improvements we were looking for we could find. Some found more, some found less and some didn’t find anything so it was a bit of a mix throughout the field.
"I think it allowed them to get an idea of the direction we are going in and the main point was that it didn’t dramatically upset the balance of the car or at least in a way that they couldn’t change with normal developments to maximise it for next season."
