Pirelli had been under pressure, particularly champions Red Bull, to move away from the early season races defined by aggressive compounds.
"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," said Pirelli motorsport director Paul Hembrey."
"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."
The company has also nominated which tyres will be used at the next three races.
Pirelli's hardest compounds - the medium and hard - will be used in Spain to cope with the high energy demands of the Circuit de Catalunya.
The two softest compounds - the supersoft and soft - will be used around the tight and twisty corners of Monaco, as has been the case since 2011.
For the Canadian Grand Prix, Pirelli will bring the supersoft and medium tyres.
