Pirelli: hard to draw conclusions from Jerez test 11 Feb 2013
Formula One tyre suppliers Pirelli were satisfied with the performance of their new tyres at the opening pre-season test of the year in Spain, but admit that conditions at the Jerez circuit made it difficult to properly assess the revised compounds.
The four days spent at Jerez, with most teams running their new cars, gave us all a good general impression of the characteristics of our 2013 tyres on track, with completely new compounds and construction, said Pirelli motorsport boss Paul Hembery.
It seems that we are very much on the right road and the changes we wanted to see are all there: the tyres are faster than their equivalents last year, and they have a wider window of peak performance.
Conditions at Jerez were not ideal this year however, as it was an extremely abrasive track - the most abrasive of all the circuits we visit all year - and consequently it was hard to draw any proper conclusions, given that the surface had actually become even more abrasive than last season. We came away with plenty of data for the hard and medium tyres, very little for the soft tyre and none for the supersoft.
Sauber rookie Esteban Gutierrez completed the most laps at Jerez - 252, equivalent to approximately 3.7 Grands Prix in distance. A total of 251 sets of tyres were used by all the teams, with the longest run - 24 laps - having taken place on the medium compound. By contrast, the longest run on hard-compound tyres was 20 laps, the longest on the soft 12 laps and the longest on the supersoft 8 laps.
The teams will have their next chance to run on Pirellis new tyres at the second pre-season test of the year, beginning February 19 at Barcelona, Spain. Although temperatures are expected to be lower than those in Jerez, the track surface should prove less abrasive.
