How Does an F1 Crew Change Four Tires in Two Seconds?



You just watched it – it was over before the question ended. So let’s slow a Formula 1 pit stop down: around twenty people, three on every wheel, and three tricks hiding inside two seconds.

Trick one: one nut per wheel, dead center. Trick two: nobody ever touches that nut – it is trapped inside the wheel, so the old wheel leaves with its nut and the new one arrives with its own. Trick three: the wheel gun reverses itself – first pull off, next pull on.

A 3D engineering breakdown of the whole stop: the nose hitting the front jack before the car has stopped (powered jacks are banned – this is muscle), four nuts loose about four tenths of a second in, the one-second wheel swap, three tenths to tighten, the button every gunner presses, the green light and the driver’s reaction time. Then how small the margin is: Monaco 2021, where one gun wee wheel came off 43 hours later, back at thefactory. And the record: 1.80 seconds, McLaren, 2023.

The phase times are a typical modern stop asmselves, not a frame-by-frame copy of therecord stop.
