Pirelli is obliged to provide the same tyres that were used in 2019 for the 2020 and 2021 seasons. With downforce and thus load levels inevitably creeping up if unchecked, it was agreed during the lockdown earlier this year to rein in downforce with revised floor regulations for next season.
However, after the problems in Silverstone the FIA has promised a further downforce cut for 2021, with tweaks in a few areas. The details will be discussed by team technical directors in an FIA technical working group meeting on Friday.
Isola has welcomed the promised changes, but stresses that reining in downforce should not be regarded as a safety measure, as Pirelli can always increase pressures to compensate for high loads. The problem is that higher pressures create other issues that impact the racing, as was seen at Silverstone.
“The FIA decided to do that,” said Isola of the change. “And I cannot say that I’m not in agreement. But I don’t want that the message to be that it’s for safety reasons, because we can use the pressure to compensate for the level of load.
“Obviously, if we consider that from now to the end of 2021 the ability of the teams to develop the cars is huge.
“We can end up at the end of 2021 with a level of load that is really very high. And therefore we are obliged to increase the pressure to where we have again degradation overheating or blistering at the
