Michelin open to F1 comeback – with 18-inch rims

1 Comment

Michelin director Pascal Couasnon says the French tire manufacturer could be open to an F1 return in 2014 – providing the sport changes its wheel rim size.

Strict rules on Formula One wheel sizes force teams to use 13-inch wheels which are considerably smaller than those seen in other racing series. Couasnon told Le Figaro Michelin would prefer to use 18-inch wheel rims if it returned to F1.

This is not the first time Michelin has mooted an F1 comeback but stipulated it must come with a concession on wheel size. It made similar noises in 2010, when Bridgestone was poised to quit the sport, but F1 eventually chose to stick with 13-inch wheels and appoint Pirelli as official tire suppliers.

The obstacles to an increase in wheel rim size are the same now as they were then. The change in size would force a costly re-think of suspension configurations and potentially put gearboxes under greater strain.

Teams are unlikely to swallow such a major shake-up in the technical rules at this late stage in the year. Particularly when they are already grappling with the cost and complexity of the new power trains.

Formula One boss Bernie Ecclestone has ruled out Michelin making a return. He is believed to have signed a new advertising deal with Pirelli which extends beyond the end of this season.

It is the FIA’s decision who will be awarded the F1 tire contract. But it is doubtful a rival constructor would want to supply tires to a series which is already contracted to advertise Pirelli’s product in future seasons.

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.
