Formula 1 tyre supplier Pirelli has announced its compound choices for the next three events, with the 'flyaway' part of the season set to begin.
As usual, the Super Soft and Soft tyres will be used in Singapore, in order to cope with the demand for maximum mechanical grip at the Marina Bay Street Circuit.
The Medium and Hard compounds will be brought to the Japanese Grand Prix due to the high-energy loads put through the tyres at Suzuka's fast circuit.
Both of these nominations correlate with the choices from 2014, but Pirelli has opted to go one step softer with its compounds for the Russian Grand Prix at Sochi.
The Super Soft and Soft tyres will be taken to the street circuit as "the asphalt has not changed significantly since its debut last year, and looking at the data from 2014, a softer step is possible."
Last year's Russian Grand Prix featured a one-stop strategy, with tyre wear a non-issue.
