The teams were able to capture most of the tyre data they needed from the single 90-minute practice session, sometimes by splitting the tyre assessment programmes over their two cars. There is still considerably less tyre data than there would be from a 'conventional' weekend, which leaves some question marks over strategy heading into the race and opens up some more options tomorrow, especially with the track evolving all the time. The teams will have a busier Saturday evening than usual analysing the performance gaps between the tyres, and working out how this can translate into an optimal race strategy. As for the tyres, we had a little bit of graining during the early part of the day, but the situation improved as expected with more running. All three compounds look set to play an important role in the race and we are satisfied with their performance.
