Is it tyres or tires? Either way, they're very important. The temperature and condition of a driver's tyres have a huge impact on their performance. 2026 sees all-new tires in F1, so what's changed? How do Pirelli choose which tyres to bring to each Grand Prix? How does the company and the FIA ensure tire fairness?

Pirelli is the Official Tyre Supplier of Formula 1. The company's Head of Motorsport, Mario Isola, joins Christian Hewgill to answer your questions. Mario explains what's different about this season's rubber, the number of tires Pirelli brings to each race and how they are allocated to the drivers.

Why don't F1 tyres have tread? Do all types of tire weigh the same? Who pays for them? Mario has the answers.

F1TV commentator and former F1 driver Jolyon Palmer joins Tom Clarkson in the Shanghai paddock to reflect on an action-packed Chinese Grand Prix.

Kimi Antonelli became the second youngest Grand Prix winner in F1 history, leading George Russell to the second consecutive Mercedes 1-2 of 2026. So can Kimi fight his more experienced teammate for the title this year?

This week on F1 Beyond The Grid
Cadillac CEO Dan Towriss on the team's first Grand Prix

Tom Clarkson is joined in the Albert Park paddock by former F1 driver Jolyon Palmer and Channel 10’s Richard Craill to reflect on an entertaining season opener in Melbourne.

Mercedes took the first victory of this new era of Formula 1, with George Russell leading Kimi Antonelli to a 1-2 finish. George might be the favourite to become World Champion, but could Kimi challenge him for the duration of the season?

Ferrari’s Charles Leclerc finished third, ahead of teammate Lewis Hamilton in fourth. Can they take the fight to Mercedes this year? And could we see Hamilton back on the top step?

Plus, the guys discuss how far behind Red Bull and McLaren are, a sensational F1 debut from Racing Bulls rookie Arvid Lindblad, points for Audi in their first race, and why there may be signs of encouragement for Aston Martin after a very challenging start to the season.
