What happened: Pirelli's wet and intermediate tyre specifications drew sharp calls for improvement following rain-affected running at the São Paulo Grand Prix. Criticism centered on compound performance in heavy spray, prompting demands for collaborative development on future wet-weather rubber.

Why it matters: Wet-weather tyre performance has repeatedly disrupted race operations and safety protocols during heavy downpours across recent seasons. With Pirelli serving as Formula 1's sole tyre supplier, compound adjustments carry significant operational stakes for race visibility and track safety.

What to watch: Formula 1 travels to Lusail for the Qatar Grand Prix ahead of the season finale in Abu Dhabi.
