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


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 “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.”

Marco Andretti to drive throwback scheme to honor 25th anniversary of grandfather Mario’s last win

Marco Andretti wanted to do something really special to honor the 25th anniversary of grandfather Mario Andretti’s final Indy car win in 1993 at Phoenix International Raceway (now known as ISM Raceway).

So the third-generation Andretti, along with his team, Andretti-Herta Autosport, came up with a plan and design that will take longtime race fans back in time when it appears early next month for the Phoenix Grand Prix.

Marco Andretti’s No. 98 Oberto Beef Jerky Circle K/Curb Honda will be decked out in the colors of the car his grandfather won his last race on the one-mile short track 25 years ago.

“When the idea of a throwback livery celebrating my grandfather’s final win was thrown around, Oberto was ready to get to the drawing board,” Marco Andretti said in a media release. “The black, white and red car resembles many of my family’s race cars and was a big part of my life growing up.

“It’s really cool to be able to add one of my cars to that family legacy.”

The car is a virtual double of the legendary Newman-Haas Racing and Texaco/Havoline-sponsored car Mario drove on that celebratory day in the Valley of the Sun 2 ½ decades ago.

Various events and ceremonies during the April 6-7 race weekend will honor the senior Andretti. That includes several of his former competitors who will be on hand to celebrate with Mario, including Emerson Fittipaldi, Bobby Rahal, Jimmy Vasser, Paul Tracy, Arie Luyendyk, and of course, son Michael Andretti and grandson Marco Andretti.
