Teams are waiting for European rounds, especially now Pirelli need to improve tyre temperature in cooler conditions. Italian tyre manufacturer will supply Super Soft and Soft tyres for Monaco Grand Prix, and Super Soft and Medium compounds for Canadian Grand Prix.
“After evaluating tyre performance over the balance of the first four races, we took the decision – in consultation with all of the teams – to change the Hard compound from Spain onwards, as we did in Barcelona two years ago when we also introduced a new Hard tyre for the rest of the season,” explained Pirelli Motorsport Director Paul Hembery.
“This latest version of the Hard compound is much closer to the 2012 tyre, with the aim of giving the teams more opportunity to run a wider range of strategies in combination with the other compounds, which remain unchanged.”
