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.”

Red Bull Air Race: Yoshi Muroya joins Sato as Japanese champs at Indy

Takuma Sato isn’t the only major Japanese athlete to take home top honors at the Indianapolis Motor Speedway this year. Countryman Yoshihide Muroya joined him in that on Sunday after winning Red Bull Air Race at IMS, and the Red Bull Air Race World Championship in the process.

Fittingly, the 101st Indianapolis 500 champion was there on site to join him in the celebration.

Muroya flew with a track-record run in the final and erased the four-point deficit to points leader Martin Sonka. The record run came after a disappointing qualifying effort of 11th in the 14-pilot field in the Master Class.

A day after the win, Muroya joined Sato in heading to Sato’s new Verizon IndyCar Series team, Rahal Letterman Lanigan Racing’s, Indianapolis-based shop.

A few social posts from Muroya’s victory and the subsequent celebration are below.

ASTLES BREAKS THOUGH AS WELL

Muroya wasn’t alone among big winners at the Speedway. In the Challenger Class, Melanie Astles of France became the first woman to win a major race at IMS, and is the first female winner in the Red Bull Air Race World Championship.

Nine women have competed in the Indianapolis 500 (Janet Guthrie, Lyn St. James, Sarah Fisher, Danica Patrick, Milka Duno, Simona de Silvestro, Pippa Mann, Ana Beatriz, Katherine Legge) and Mann is the first woman to have been on the pole position at IMS, having done so for the Freedom 100 in 2010 in Indy Lights.
