Mercedes AMG F1 W09 EQ Power+

The stewards decision focuses nearly entirely on the holes in the spacer and not the holes in the wheel. I think that they're creating a low pressure area inside the wheel hub via the rotation of the holes that pass through the spokes.
This in turn draws air through the small holes in the spacer, which gets its air from the drive lug holes. I'd be willing to bet if we saw behind that spacer we'd see a number of holes there divisible by the number of spokes.

Also noticed that.

I had a little look at the biographies of the stewards. None of them studied any technical or engineering studies. Gerd Ennser, for example, is a lawyer and director of a court. His hobbies are motor sports. All team engineers and also a big amount of users of this forum most probably have a lot more technical knowledge and look at things differently.

Also talking generally: Is it always the case that stewards are people who actually don’t even have the quarter of the technical level team engineers have? If yes, that’s shocking.

Deciding a complex technical question by just having motor sports as hobbies.. makes big sense.

You're making a category error here. You are comparing two groups on account of their credibility here but selecting for formal competence in one case and informal in the other. That's clearly not fair. You might just as well speak of the stewards as having "a lot more technical knowledge" than what "the big amount of users of this form" would have - it's just as given. The fact that it is easy for someone to think of me as having the level of, formal or informal, competence most suited for some argument does not make it so. Or right.

So you might know that the stewards don't have some amount of formal competence that you deem necessary for the adequate execution of some task. But since you _don't_ know the formal competence of the group you put them against, you can't assume that it has to be adequate because they appear knowledgable on average.

An unknown does not become a known on account of appearances.

In most sports it’s enough to know the rules to be able to referee. In Formula 1 it’s not enough to know the regulations, you also need to have enough competence to understand every detailed aspect to decide if a technology on a car matches the regulations or not. To decide if a complex aerodynamic detail is legal you need to be on the level of an aerodynamicist, else it just doesn’t make sense. A person who has not studied and been into a particular engineering subject, surely can’t be on the same level of competence. Especially in F1 where the pinnacle of engineers push each other to come up with innovations.

But that’s enough off topic.

And you'd have done that and objected to their apparent lack of expertise if they had thrown Mercedes's wheels out? No? Thought not.

The official statement of he stewards seemed so inaccurate and mostly pointing out the little holes. And because I saw the names of the stewards I was curious and had a look. Now I learnt something which I find stupid in general.

[subcritical71]

So, you don’t think the stewards have access to FIA or other experts in their field? How many experts do you think would be needed to come to a decision (aero, materials, suspension, thermodynamics, etc). Now think of the whole car plus officiating the race, you’d need 100 experts. How consistent do you think those decisions would be.

You are drastically overvaluing formal education, some of the dumbest people I've ever worked with have had phds!

A few experts for aerodynamics, engine, chassis and probably all the regulational questions occurring throughout a season can be answered.

If stewards are being supervised by other FIA experts in such questions, then it’s technically not the decision by the stewards themselves.

I believe you, but those dumb people would then not be working for FIA or Formula 1.

I don’t believe that are supervised by experts but being advised by an expert. In this way the stewards are still able to collect information, whether it be technical or expert opinion, and decide the applicability of the rules themselves.

[Flanker27]

Mercedes given the all-clear to run the wheels as designed.

So, everyone will run such systems in the near future. Going to be fun next year when 30% of the solutions are then declared illegal because they could have aero importance.

For motorsport.com his decision apply only to this race... in next races different panels may have different opinion

[bosyber]

Though that may just be because these stewards only decide on this race, right (and so only decided on this particular implementation of this idea).

[pimpwerx]

Why i disagree with scarbs is blowing hot air through the wheels cannot keep heat away from them. You are actually putting heat into them. What he is saying would make sense if the wheels were already hot, and fresh cool air is being blown in to drive away that heat.
Cooling of the wheel is better done by having a brake duct that simply diverts air into the rim annuls.

I think the cooling theory makes the most sense, just based on how Merc behave on the grid. They consistently remove the rear tire warmers before the fronts. If they wanted to heat the tires with these wheels, they would keep the warmers on the rears longest. This is not the case, so they're somewhat undercutting the purpose of these wheels, if they're really for heating the tires.

[Just_a_fan]

The Mercedes has been good in wet conditions too, a situation where it's easy to cool the tyres too much. Even wets need heat in them, albeit less than slicks. Everything this season points to them needing to prevent heating of the tyres, not designing wheels to make them hotter.
