Pirelli chief Paul Hembery has confirmed that the Italian tyre supplier will make changes to its F1 rubber in time for the Canadian Grand Prix.
Hembery had admitted after the Spanish Grand Prix
in Barcelona that the widely-used four-stop strategy had been 'too much'
amidst concerns over the levels of degradation suffered throughout the Catalunya race.
Following discussions in the aftermath of the race, Pirelli has now revealed that changes are to be made to the tyres in order to reduce the number of stops made during the races.
A target of two or three stops per race will be the aim, with Pirelli seeking to be less aggressive without putting those who had already mastered the tyres at any kind of disadvantage.
“Our aim is to provide the teams with a new range which mixes the stability of the 2012 tyres and the performance of the current ones," Hembery said. "As a company, we have always moved quickly to make improvements where we see them to be necessary. After evaluating data from the first few races this year, we've decided to introduce a further evolution as it became clear at the Spanish Grand Prix
that the number of pit stops was too high.
“The Spanish Grand Prix
was won with four pit stops, which has only happened once before in our history. These changes will also mean that the tyres are not worked quite as hard, reducing the number of pit stops.”
Hembery added that some of the issues currently being encountered were down to the a lack of testing opportunities in-season, with the current tyres having only been tested in lower track temperatures encountered over the winter.
The motorsport chief also said that steps were being taken to reduce the number of delaminations that have been seen so far in 2013.
"With limited testing time, it's clear now that our original 2013 tyre range was probably too performance-orientated for the current regulations,” he continued. “However, having identified this issue, we're determined to rapidly resolve it.
