Pirelli will implement changes to their 2013-specification changes sooner than planned following criticism for Formula One boss Bernie Ecclestone.
Formula One’s official tire supplier announced on Tuesday it will bring revised compounds in time for the Canadian Grand Prix instead of the British Grand Prix, as they had previously indicated.
The changes to the tires aim to prevent drivers from needing to make four pit stops per race, as occurred in Spain, and to address the delamination problems that have been seen.
“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,” said Pirelli motorsport director Paul Hembery.
“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.”
“We’ve also taken this step to avoid the delaminations that were caused by track debris,” Hembery added.
“It’s important to point out that these delaminations, which occur when the tread comes off, do not compromise the safety of the tyres as the core structure of the tyre is not affected in any way, helping drivers to complete the lap and to change the damaged tyres safely. These delaminations were due to damage from debris that overheated the tread.”
Felipe Massa suffered two tire failures during the race in Bahrain, Lewis Hamilton had a tire problem during practice for the same race, and Paul di Resta had a similar failure during practice in Spain.
Ecclestone criticised Pirelli following the Spanish Grand Prix, which saw drivers make a total of 77 pit stops.
“The tyres are wrong, not what we intended when we asked Pirelli to produce something which did a half race,” Ecclestone told the Daily Express.
