Pirelli would only change tyres if it was a safety concern

The 2019 tyres are 0.4 mm thinner that the previous year which reduces the blistering and overheating but has created a difficult working area for the tyre to have optimum performance.

Mercedes have had all the success so far this season and seem to have grasped the demands of the news tyres better than the rest.

Amid the speculation and concerns from teams such as Red Bull and Ferrari there has been no official request to Pirelli to revert the tyres back to last year’s spec.

Pirelli’s F1 boss Mario Isola said to Motorsport: "It is very clear how you can modify the construction or the compounds during the season.

"I didn't receive any request so far. If I receive a request that is reasoned, we will consider that request. We will consider what we have to do to modify the tyres, and we will discuss that with the FIA.

Isola admitted to achieving most of the targets for 2019 but also that the working area for the tyres was a concern which Pirelli are working to improve for the rest of the season.

But also that it was now up to the teams to work their car around the tyres.

"How to design the car, how to generate the downforce, to design the suspension, is their job," he added.
