Pirelli unchanged as teams stymie plans
Tyre supplier confirms compounds will remain the same after insufficient testing and lack of agreement amongst teams.
The next three grands prix - in Britain, Germany and Hungary - will feature compounds from the original 2013 Pirelli tyre range after failure to agree on the introduction of new rubber from Silverstone.
Although Pirelli claims that plans to introduce a revised compound on the grounds of safety were compromised by the lack of testing prossible due to the rain-hit practice sessions in Canada last weekend, it also makes it clear that a lack of unity between the eleven F1 teams also made it difficult to press ahead.
The manufacturer, now in its third season as the sole tyre supplier since taking over from Bridgestone at the end of 2010, made the revelation as it released details of the compounds for each of the next three races on Thursday afternoon.
“At the British Grand Prix, the hard and medium tyres have been nominated - the two hardest tyres in Pirelli's range - which will be best suited to the high-energy demands of the Silverstone track," it explained, having had to do away with plans to give its revised medium compound a race debut at the UK round.
“In Germany, the medium and soft have been selected, [as] the Nürburgring is a circuit with varied speeds and corners, plus heavy braking areas. The tarmac roughness is very low, so plenty of mechanical grip from the tyres is required.
“For Hungary, Pirelli will bring hard and medium compounds. Hungary is the slowest permanent track on the calendar, but it still places a lot of demands on the tyres due to its twisty layout, which means that the tyres move around much more than on a fast and flowing track.”
The most telling part of the announcement, however, underlined the tyre-inspired rift between teams, with some pushing for change on the grounds of safety - notably Red Bull and Mercedes - and others resisting the introduction of a new compound, having got their cars working well on the rubber originally slated for the entire season. Force India and Lotus spearhead the latter group, both having performed above expectation in the early part of the season.
"The tyre construction will remain unchanged, contrary to Pirelli's initial plans," the communique confirmed, "This decision is due to the fact that the new tyres, which were brought to the Friday free practice sessions in Canada, could not be tested sufficiently due to rain – and that the teams failed to agree unanimously about introducing the changes.
"Instead a change in the tyre production process should now ensure that the delamination issue has been addressed."
The problems, which affected Ferrari, Mercedes and Force India most publically of all, have apparently been tackled with the use of different glue to bond the tyre together. Each compound will continue to use the steel band introduced for 2013, rather than the kevlar example that Pirelli had hoped to employ, initially in Montreal, and then at Silverstone.
