Report: Pirelli now eyeing 19-inch F1 tires, not 18-inch

7 Comments

During last month’s Formula One test session at Silverstone, Lotus reserve Charles Pic turned laps on Pirelli tires fitted with an 18-inch rim.

But while Pirelli motorsports director Paul Hembery (pictured, with one of the 18-inch tires) said that he got good feedback, he did say at the time that a 19-inch tire could be “probably more interesting going forward.”

Sure enough, Hembery’s now confirmed that his company’s focusing on 19-inch tires for future seasons as F1 ponders ways to become more road-relevant.

“We are doing a lot of work – probably focusing on 19-inch now, if I am really honest with you,” Hembery said according to Crash.net. “We are carrying on our work internally on those developments and so from our point of view, it goes ahead.”

The F1 teams would have to give their consent for such a tire change.

After Pic tested with the 18-inch tires – which could be introduced as early as 2016 if necessary – Lotus technical director Nick Chester explained how a bigger tire would have major impact on car design and would need an extended testing calendar leading up to a debut.

As for what the width of the 19-inch tires would be, Hembery said that would ultimately come down to several factors.

“I think that depends on what package of aero changes they are going to make and what they think they might do with the suspension,” he told Crash. “We have heard talk of some form of active suspension. I am not sure if that is going to happen or not.

“But there is a lot of aspects they are talking about which could change what we do with that.”

While failing to hit the podium as he did in both 2015 and 2016, Sergio Perez once again finished the year as Formula 1’s leading midfield team driver, but faced a greater fight from within Force India in the shape of Esteban Ocon.

Perez has long been knocking on the door of F1’s top teams should an opportunity come up, and 2017 saw him continue his solid if unspectacular form. The dominance of Mercedes, Red Bull and Ferrari meant any finish higher than seventh was impressive, something he managed to do on five occasions.

But there were some missed opportunities along the way, most significantly in Baku. Force India had been quick all weekend, with Perez charging to sixth on the grid, and when drama struck at the front, he and teammate Ocon were eyeing a podium finish as a minimum.

Contact between the two forced Perez to retire and prompted Ocon to pit for repairs, leaving the team without the top-three finish it targeted heading into the season. With Lance Stroll taking P3 for Williams and Daniel Ricciardo winning the race, a maiden victory for Force India was not out of the realm of imagination.

Perez and Ocon came to blows on a number of occasions, with the final straw coming in Spa when they twice touched on-track, prompting Force India to introduce team orders. Perez finished the year 13 points clear of Ocon in the final standings, meeting his own pre-season target of 100 points, yet the Frenchman had arguably made the bigger impression at Force India through his first full season in F1.

Force India remains the top underdog in F1 with Perez spearheading its charge, but it is difficult to see either taking the final step to becoming true contenders at the front of the field anytime soon, as solid as their displays have been.

Season High: P4 in Spain after retirements for the ‘big three’.

Season Low: Losing a sure-fire podium, if not a win, in Baku after contact with Ocon.
