This year Pirelli has made tyres far more resistant to degradation and overheating, circumstances for which we expect less pit stops and runs much longer than in previous seasons.
despite this, in the Grand Prix of Spain Pirelli selected the three compounds-hard, but the teams rejected the hard to consider it excessive. The own Mario Isola, manager of the Italian brand, acknowledged that the election had not been adequate and of face-to-Silverstone, changed the selection initially planned.
For the Hungarian Grand Prix, Pirelli does not want to go with that tonic and remained the intermediate compounds in anticipation of the usual heat of Hungary at the end of July could pose problems with the compound ultrablando, despite the fact that it is a slow track in which, however, there are several low to medium speed corners and long radius provide lateral loads to the tire, accelerating its degradation.
face the Malaysian Grand Prix, Pirelli acknowledged implicitly that the compound most resistant of the range of 2017, the hard, is not suitable even for the suffocating heat of Malaysia, which also has a circuit with fast corners and long in the lateral forces exerted on the tire are important. And the confirmation that you will not see the hard compound in the entire season has come with the election of Suzuka, a track with a huge requirement of side loads on the tire.
on the other hand, another of the circuits that has more quick turns, Spa-Francorchamps, you will see for the first time as you use the tire ultrablando in competition.
