Pirelli has elected to make just one minor change to its hard-compound tire for the remainder of the season, following a meeting in Milan earlier this week to decide if it needed to revamp its products.
Red Bull had championed a push to try and make Pirelli move away from the more aggressive compounds that it introduced at the start of this season. However, a majority of teams were happy with what Pirelli had produced this season and were eager for the Italian company not to make any major changes.
Pirelli chiefs met at their headquarters earlier this week to analyze the situation, and in the end the only change will be to the hard compound, to improve its temperature working range for the likely cooler conditions that teams will be greeted with during the European phase of the season.
"After evaluating tire 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 onward, as we did in Barcelona two years ago when we also introduced a new hard tire for the rest of the season," Paul Hembery, Pirelli's motorsport director, explained. "This latest version of the hard compound is much closer to the 2012 tire, 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."
F1 teams will get the first chance to try out the new harder compound tire at the forthcoming Spanish Grand Prix, where it will be used with the medium-compound tire.
Pirelli has also confirmed that in Monaco the soft and super-soft tires will be used, while in Canada teams will have the super-soft and the medium.
Although Red Bull has won two of the first four races, and is leading both championships, team principal Christian Horner said after the Bahrain GP that he was still unhappy with the rubber choices.
"I think the tires are still too on an edge," he said. "Needing to four-stop in a race is I think a bit too extreme. There are other teams that look like they have bigger issues than Red Bull with their tires, but you need to speak to them to ask their opinion. But I do feel the tires are on an edge and just need to come back a little bit."
