Pirelli will only remain Formula 1's exclusive tyre supplier if the sport continues to provide the Italian company with a "technological" challenge said its CEO Marco Tronchetti Provera.
With a fundamental transformation on the way on all fronts, Formula 1 aims to build a new foundation from which to prosper beyond 2021 when it ushers in a new set of regulations.
Pirelli's boss hopes the company will very much be part of F1's future, but only if it continues to promote technological excellence.
"If the challenge continues to be technological, giving the teams and drivers what they want, then we are here to do it," Tronchetti Provera told Italy's national radio broadcaster RAI.
"But if it becomes a commercial event, we will withdraw. So if the path remains we are there, if it doesn't we will not be.
Pirelli's current supplier deal with F1 expires at the end of 2019. While some drivers have leveled criticism at the company's compounds this season, Tronchetti Provera believes the action has been generally good this year, with the exception of last Sunday's Monaco procession.
"The important thing is that the drivers are more and more at the centre. I believe the tyres work when the drivers are happy, and the public is happy when the drivers are able to have a challenge," he said.
"The competition this year is generally more lively and that is good news.
"But it is clear that with the increase in the performance of the cars, both with aerodynamics and the tyres, overtaking at narrow circuits has become practically impossible."
