Pirelli to investigate di Resta’s tire failure

Leave a comment

Paul di Resta suffered a tire failure at high speed entering the pit straight during Friday’s second free practice session for the Spanish Grand Prix. Pirelli announced shortly thereafter that it will investigate the matter further.

“Obviously there was a problem in the final part of FP2 that affected the medium tire on the Force India of Paul di Resta and we’re going to investigate the cause of that fully,” Paul Hembery, Pirelli’s motorsport director, said in a post-practice release.

While drivers seemed happy with Pirelli’s newly modified hard compound, which was introduced this weekend, the medium appeared to have been affected by higher tread temperatures. Hembery explained further when asked by Autosport after practice.

“It doesn’t look pretty when you get the tread coming away like that,” he said. “If anything like that happens, it tends to collapse the tire on to the rim, so it did not look good. This year we are seeing the tread coming away. Visually it looks rubbish. We don’t like that and we are looking at seeing if there are things we can do to eliminate that.”

For better or worse, Pirelli’s 2013 tire compounds have been in the news more than you might like to hear or see this year.

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.
