For the first time this season, teams will get to see how Pirelli’s hard compound tyres drive at the Spanish Grand Prix in two weeks time.
As part of the 2016 regulations, Pirelli have to make three of their five dry weather tyres available at each race.
However, at the expense of the supersoft compound, team across the grid seem to be trying to avoid using the hard compound as the medium and soft compounds dominate their tyre selection ahead of the Spanish GP.
Ferrari and Haas have each chosen eight sets of soft compounds, one more than Mercedes, which will make them the most aggressive teams on the Circuit de Barcelona come race weekend.
