F1 News: Pirelli Boss Mario Isola Has Confirmed That Tyre Pressures Will Be Changed for This weekend’s 70th Anniversary Grand Prix
After the first round of British GP where late drama changed the course of the race, now Pirelli the official tyre supplier has come up with the possible solution. In British GP Valtteri Bottas, Carlos Sainz & Lewis Hamilton suffered tyre issue. Only Hamilton was luck and went on to win the race even with puncture in left front, however, Bottas, slipped to 11 from 2nd and Sainz slipped from 4th to 13. Pirelli boss Mario Isola has confirmed that tyre pressures will be changed for this weekend’s 70th Anniversary Grand Prix, also being held at Silverstone.

Mario Isola On The Tyre Issue
“We are going up by 2psi front and 1psi rear,” Isola confirmed. As a result, teams will be running 27 psi for the front tyres and 22 psi for the rears, and with the softer compounds in play, Isola said he is expecting the teams to have to run a two-stop strategy.
“I believe that because we are going with a one-step-softer compound, the length of the stint will be shorter by definition because the compounds are softer,” explained Isola. “Consider that the medium compound will be the hard for this weekend, the only one that was running 36 laps [in the British GP] was [Romain] Grosjean and the tyres were finished, so I struggle to believe they can run more than 30-something laps next weekend.”
“As a caveat, he added: “They [the teams] are very good at managing the tyres so I cannot write that in stone, but, looking at the softness of the compound, probably most of the teams will target two-stop strategies…”
Isola said the tyre issues from the British GP will also have an effect on tyre choices for the upcoming races at similarly high-speed Mugello and Spa-Francorchamps, plus Portimao – as well as next year’s compounds.
