When putting tires on a personal vehicle it’s always recommended to tighten the lug nuts in a star or criss-cross pattern, yet when you see pit crews for nascar they just go around one by one very quickly in a circle, why can they get away with doing it that way even though they’re driving much faster so things like a loose lug nut or vibration should be a pretty big deal, but it’s recommended that I always do a star or crisscross pattern?

The race cars races around a track in relatively known and observed condition for a short amount of time, the wheels will be replaced or serviced within minutes to a few hours of the last fitment. Most race teams will even have a tyres and wheel team member that
Watches the wheels via an under chassis camera set. A race tyre will only do about 200-800km in its life.
The home car will be used for long periods of time where no one checks the wheels for seasons. The home wheels will endure thousands more heat cycle events,wet/dry weather cycling events, Freezing thawing and many more miles of constant vibration, most doing 10,000 to 40,000km unchecked. Now most drivers will say “I check mine every bla bla bla…..” but in reality alot… too many people just don’t check tyres or anything for that matter. Thus more rigid expectations should be had for the home game.
These all roll alongside you one roads and streets carrying families and individuals at high speed everywhere.
The commercial tyre is another level again, these in most countries with road rules have huge requirements on wheel lug torque, this is due to them doing even more heat cycling and longer durations of vibration, with life spans expecting 100,000km+.
Sometimes pointers called lugnut flags are used to indicate no lug movement.
