Formula One tyre supplier Pirelli are predicting a one or two stop strategy in Sunday’s 63 lap Emilia Romagna Grand Prix at the Imola circuit in Italy.
The optimal strategy is a one stopper, starting on the P-Zero Yellow Medium tyre and the P-Zero Red Soft tyre, using the Soft tyre for 28-30 laps and the Medium tyre for 33-35 laps either way around.
Very close to that is a soft to hard strategy: soft for 24 to 27 laps and hard for 36 to 39 laps (or vice versa).
Third-quickest is medium for 26 to 35 laps and hard for 28 to 37 laps. This strategy has the advantage of featuring a wider pit stop window.
A two-stop strategy is slower, but te best one is with two stints on soft of 18 laps, plus one stint on medium of 27 laps.
Mario Isola, Pirelli Head of F1 and Car Racing says:
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.”
