Order Reprints

Tire sets brought to Jerez: 284 of which 5 supersoft; 37 soft; 120 medium; 57 hard; 40 intermediate; 25 full wet. Tire sets used:  155 of which: 0 supersoft; 21 soft; 83 medium; 29 hard; 16 intermediate; 6 full wet.

Pirelli motorsport director Paul Hembery:
“The four days at Jerez were quite a straightforward test, with all the teams present getting in a lot more running than they did at this time last year: which just goes to show the phenomenal rate at which this hybrid technology has developed. We experienced varied weather conditions on a very abrasive track at Jerez and encountered no issues, with generally positive comments from the drivers. From a tire perspective, the two tests in Barcelona later this month will be more representative, as long as the weather remains favorable. The provision of our ‘winter hard’ prototype compound – a specially created testing compound, with a fast warm-up – was clearly appreciated, as the drivers used it extensively. It’s clear that the new cars have already evolved a lot since 2014, and we anticipate further improvements before we reach Melbourne in March.”

Pirelli’s special ‘winter hard’ prototype tires (16 sets) were also brought to Jerez. Two sets of these are available per team for the total of the three pre-season test sessions. The ‘winter hard’ is a prototype tire strictly for testing purposes only, which will not form part of the P Zero range in 2015. It is a hard tire with a low working range compound, which allows it to quickly reach top performance even in cool conditions: well suited for European weather conditions in February.
