Pirelli has confirmed the tyre compounds that it will bring to the Spanish and Candian Grands Prix later this year.
The Italian marque has not yet confirmed what compounds it will bring to the Monaco Grand Prix at the end of May, that precedes the races in Spain and Canada.
Pirelli will bring the C1, C2 and C3 compounds to the race at the Circuit de Catalunya, the same sequence it will send to Bahrain.
The softest compound, the C5, will make its first appearance of the year at Circuit Gilles Villeneuve along with the C4 and C3.
Pirelli has cut its range of seven dry compounds from 2018 to five for 2019.
