Mercedes and Red Bull have opted for the maximum number of the unraced ultra-soft compound for the Monaco Grand Prix, with all teams favouring the brand new compound which makes its debut in Monte Carlo.
Every driver pairing, bar Renault's Kevin Magnussen and Jolyon Palmer, have opted for the same number of each, with Lewis Hamilton, Nico Rosberg, Daniel Ricciardo and Max Verstappen taking ten sets of the ultra-soft, two of the super-soft and one of the soft.
Meanwhile Ferrari have opted for one less set of the ultra-soft for an additional set of the softs for both its drivers – a strategy uncopied by any other driver.
Manor's Pascal Wehrlein and Rio Haryanto have opted for the fewest sets of the ultra-soft at just six, instead choosing five sets of the super-soft and two of the soft.
