Mercedes releases side-by-side of 2017 vs. 2016 Pirelli tires (PHOTOS)


Tire testing of the new, wider Pirelli tires from 2017 and beyond kicks into high gear this week and really, this month of September.

Ferrari is undergoing a two-day test at Barcelona’s Circuit de Catalunya; meanwhile at Le Castellet in France, Mercedes AMG Petronas is hitting it hard at Circuit Paul Ricard for a three-day test.

Mercedes ran Pascal Wehrlein in a modified version of the Mercedes W06 Hybrid, for today’s running at Paul Ricard.

Mercedes will also do two more days of testing at Paul Ricard on Sept. 21-22.

Pirelli has confirmed the new front tires will be 305mm wide compared to the 245mm width today, and the rear tires will be 405mm wide compared to 325mm today.

Here’s some photos of the side-by-side comparison of the 2016 tires versus the 2017 tires, thanks to Mercedes.

The NTT IndyCar Series will be sharing Indianapolis Motor Speedway with the NASCAR Cup Series in a race weekend doubleheader for the second consecutive season, but both series will be on the road course in August 2021.

IMS announced Wednesday that IndyCar will hold an Aug. 14, 2021 race on its 14-turn, 2.439-mile road course. It’ll be a day before NASCAR’s premier series runs the same layout for the first time after the Brickyard 400 was contested on the 2.5-mile oval for the first time in 27 years.

This season’s rescheduling of the IndyCar GMR Grand Prix to July 4, 2019 (a day before the Brickyard 400) led to the first NASCAR-IndyCar doubleheader weekend. The Xfinity Series also raced on the IMS road course for the first time July 4 after the IndyCar race ended.

INDYCAR AT IMS THIS WEEKEND: Harvest GP schedule, entry lists

IndyCar will be holding its second race weekend this year at the IMS road course Friday and Saturday with the Harvest GP.

“Our first NASCAR-INDYCAR weekend was a big success last July, with positive feedback from
our loyal fans who watched the races on NBC and from the drivers, teams and participants
involved,” IMS president Douglas Boles said in a statement. “The Xfinity Series’ debut on the IMS road course provided exactly the kind of thrilling action from the green to checkered flags that we anticipated, so we know the teams and drivers of the Cup Series will put on a great show as they turn left and right for the first time at IMS.

“We can’t wait to welcome back fans to see NASCAR and INDYCAR together during this
exciting weekend as we add another memorable chapter in the long, storied history of the
Indianapolis Motor Speedway.”

It also will mark the first NASCAR Cup-IndyCar doubleheader with a crowd as fans weren’t permitted at IMS in July because of the novel coronvavirus (COVID-19) pandemic.

Over the course of Wednesday, NASCAR is releasing its 36-race slate for next season. IndyCar has yet to release its full 2021 schedule.
