With the new generation of 2017 cars, we may see lower or similar top speeds to last year, but with more energy going through the tyres because of the extra downforce under the new regulations. This combination of speed and downforce defines the amount of work that the tyres have to do. The tyre choice has also been influenced by the risk of blistering at Monza, as there are plenty of braking areas in a straight line. This means that the cambered shoulder area of the tyre can easily overheat and so cause more blistering compared to other circuits. In the past Monza has given us many different types of weather, but following a very hot summer, it’s reasonable to expect more high temperatures over the weekend. How this influences tyre behaviour is likely to be a focus of free practice as the teams examine different potential strategies
