Under 2 seconds for F1. I remember Scott Russell at the Daytona 200 in the mid 90’s, he pulled in for front and rear wheel changes ( not sure about fuel now) on a yzf750 was 6.6 seconds that was real impressive.

I had a YZF750SP & can't even contemplate changing wheels in 'that time'. The F1 one, man, blink & you miss it. I put it on .25 speed to see what's going on.

Like to see only 4 pit crew members doing the changes now-a -days. Would be a tad slower than 2.5secs methinks. Took a guy 35mins to fix a puncture for me at a tyre place recently.

Agreed. A proper real world comparison would be the same number of pit crew. Still impressive with modern methods but simply not the same crew limits

I suspect it would take longer than 35 minutes to mount, test and balance an F1 tyre on to the wheel.

the rearstyres on the F1 car that I worked on could be fitted by hand. so fit, blow it up, tighten safey bolts, and balance 5 minutes per wheel.

Maybe should be limited to seven. One per corner, one for the stop/go board and two for the jacks? If they also need a new nose cone, too bad, have to wait.
From the video, Ferrari had 21 personnel.
The chap front right of the Indy car took rather a lot of hits to get the wheel spinner off - and just five or six to put it back on.
As an exercise for students doing time study and time estimating, it was always a hoot to set them the estimation test of changing all four wheels on a saloon car, 4 wheel nuts, no hubcaps, with one scissor jack, jacking one corner at a time, and a spider wheel brace.
Afterwards, we'd go out to the car park and I'd get a volunteer to actually do the job, so that they could time and rate it and come up with a Standard Time for the job. (For those not familiar with Standard Time in Work Study, it includes rest and contingency allowances.)
Some hilarious estimates - but usually about 400% wrong.
