Spanish GP practice quotes: Pirelli

"The rain meant that we don't have a full set of dry data to analyse this evening, but the initial feedback from the drivers about the new hard tyre - which has a wider working temperature window - is extremely positive. There is still a lot of track evolution to come: so far we are seeing a difference of just under a second between the two compounds and high wear, which is to be expected on an aggressive track like Barcelona, but we would expect that to come down a bit over the rest of the weekend, which has a consequent effect on degradation.

"We'll be able to make a more accurate prediction after the final free practice session and qualifying tomorrow. Obviously there was a problem in the final part of FP2 that affected the medium tyre on the Force India of Paul di Resta and we're going to investigate the cause of that fully. Whatever the cause, this is not something we like to see and once we have established all the facts we will decide whether some further modifications to the tyres are required to help avoid this type of issue."
