Pirelli have announced their tyre choices for the F1 2018 Australian, Bahrain and Chinese GPs.
Marcch's season curtain-raiser in Melbourne will see Pirelli's soft, supersofts and ultrasofts being used.
The medium tyre will be used in Bahrain along with the soft and supersoft while the medium, soft and ultrasofts have been selected for China - but not the supersoft, the compound 'step' between the softs and ultrasofts.
The new-for-2018 hypersoft compound won't be used in the opening three rounds and its debut may be delayed until May's Monaco GP.
Pirelli have nine tyres available for 2018 after adding both the hypersoft and the superhard to their range.
