Sports Mole rounds up all of the latest news regarding Formula 1 on Tuesday, September 29.

Tuesday morning's Formula 1 news roundup:

Huge F2 crash may reveal 18-inch tyre flaw

F1's governing body will look into whether there is a safety problem with the sort of 18-inch wheels that are set to be introduced in Formula 1 in 2022.

Although the corona crisis has put back the introduction into F1 until 2022, the Formula 2 field is using 18-inch Pirelli tyres for the first time this year.

On Sunday at Sochi, a frightening and ultimately fiery crash between Luca Ghiotto and Jack Aitken forced the abandonment of the Formula 2 race.

Afterwards, some observers wondered if the crash highlighted a problem with the 18-inch design that causes a sudden puncture with even light contact.

"I hadn't noticed that," Daniel Ricciardo said on Sunday when asked about the incident and the potential link with the 18-inch wheels.

"I'm just glad that the drivers are ok, but I am sure that all the parties involved will look into whether there are any problems with the way the new wheels work."

F1 race director Michael Masi was asked the same question, and he also admitted he has not thought about whether the 18-inch design is inherently problematic.

"To be honest, regarding this incident, I was primarily interested in the condition of the drivers and the restoration of the barrier," he said.

"But the FIA always pays attention to these things, so I'm sure that together with Pirelli we will investigate it after the weekend, as is the case with any other serious incident."

Perez would accept Red Bull offer

Sergio Perez says he would "without a doubt" accept an offer to become Max Verstappen's teammate at Red Bull.

At Sochi, two weeks after his ousting from Racing Point became official, rumours swept the paddock that the Mexican driver had inked a pre-agreement with Haas for 2021.

The rumour indicated that the news could be made official this week.

"Nothing has been signed yet, but there is some progress," Perez said after Sunday's Russian GP.

"Let's see how things go. Neither myself nor the teams have any rush, so let's wait a bit."

Some sceptics of the Perez-Haas rumour indicated that the 30-year-old driver might not be interested in joining a small back-of-the-grid team like Haas.

"I need a project that motivates me to get up every morning, train and travel all over the world," Perez told the Spanish broadcaster Movistar.

It is notable, therefore, that another rumour is that Red Bull may be interested in signing Perez to replace Verstappen's struggling teammate Alex Albon.

"Our intention is absolutely to retain our current drivers," Red Bull boss Christian Horner said when asked about Perez and also Nico Hulkenberg's availability.

"Alex is our preferred choice," he added. "Inevitably, you have to be aware of what other options are out there but our absolute preference and likelihood is to retain our existing driver lineup."

However, when asked about Red Bull, Perez made it clear that he would not hesitate to say 'yes' if an offer was made.

"Without a doubt," he said at Sochi. "It is a team that is definitely going to fight for championships in the coming years."
