We’re seeing the hard tyres in Brazil for the first time since 2013, which should prove to be very effective against the high-energy demands of the track. In 2015 we had a three-stop race, so with the increase in performance and downforce this year, taking a harder tyre – which has nonetheless been a very rare occurrence this season – was the only sensible option to offer a number of different strategy variables. Balancing its durability against the extra performance of the softer compounds will hold the key to the race tactics. The weather will obviously play a big part in these calculations too.
