Christian Horner has raised concerns about Pirelli’s 2020 tyres after the drivers weren’t happy having tested them at the Circuit of the Americas on Friday.
The drivers were given a set of Pirelli’s 2020 C4 tyres to run.
While some opted for just a few laps, others such as Lewis Hamilton spent almost the entire 90 minutes putting the tyres through their paces.
The teams, though, weren’t particular happy.
Horner said: “We’ve agreed to take the time to analyse what happened here.
“The tyres weren’t a positive step here this weekend.
“I think that was unanimous up and down the pit lane, but we have agreed to take a couple of days to study data and try to understand why.”
“I think we will stick with what we have if what is proposed isn’t better,” he said.
