Taking bets on who is the first team to run chrome hubcaps!
Maybe AT will have white ones?

With the 2022 rule change on the horizon bargeboards will no longer be a feature of F1 cars, but what are they, how do they work, and will F1’s designers be able to replicate their function in 2022?
Carbon and presumably just push into the rim to seal it like an old skool hubcap.
SSC is Standard Supply Components - so design and manufacture will be performed outside the teams. Wheel rims are also SSC parts - looks like BBS has the contract?!3.13.7 Wheel Cover
A single Wheel Cover per wheel, must be rigidly secured to the wheel rim such that it has the same rotational velocity as the wheel it is connected to and forms an aerodynamic seal to the wheel rim. The outboard surface of the Wheel Cover must be made to the geometry defined by RS-FWH-COV for the front wheels and by RS-RWH-COV for the rear wheels.
The Wheel Covers are classed as SSC.
Looks like not in 2022. It's been redacted from 3.13.7
There's a much better chance another series could buy the same tires. Currently there's little to no chance, 13 inch rims just aren't used anywhere else. F2 is currently using 18 inch tyres. The end product might not be identical, but some of the production process can be re-used as 18 inch is a much more common size. It's also closer to the development of tyres used in the real world, Michelin rejected a return to the sport on the basis 13 inch tyres have no significant real world applications and didn't want to invest in developing them just for F1.Hoffman900 wrote: ↑11 May 2021, 15:48I’d have a hard time believing that the tooling for the F1 cars would ever be used for other series.Diesel wrote: ↑11 May 2021, 14:31It's also about tooling, there's no other series is using the same size tyres as F1 currently, so it's very expensive for tyre manufacturers to run a production line for just a single racing series. In theory, moving towards the larger and more common wheel size opens the door for the tyres to be used across multiple different series. It then becomes a lot more cost effective for the tyre manufacturer as they can sell the tyres beyond the 10x teams in F1.
Plenty of tire manufacturers make less volume than the F1 tires.
F2 is only using 18s because F1 is going to change, however F2 tyres are the old F1 widths - 275mm front and 325mm rear treads, with a 705mm inflated tyre diameter. F1 tyres will be 270mm and 405mm with a 725mm diameter, LMPH tyres are 310/310mm or 290/340mm with a 710mm diameter. There's just no sharing of moulds - the construction and profile is tailored to the application, which for F1 is high lateral G and huge power.Diesel wrote: ↑12 May 2021, 10:57There's a much better chance another series could buy the same tires.

I never said the moulds were literally reusable, just that generally more of the process and tooling would be resuable, probably more in an R&D sense than a quite literal using of the same tooling to produce two different tyres. F2 switching to 18 inch is my point, it was done in prep for the F1 switch so Pirelli could start learning a bit more about developing the tyres at this size on something that has similar geometry etc. to an F1 car i.e. there is crossover in development of the tyres across bother series even though the sizes aren't exactly the same. And I still maintain the 18 inch tyre produced for F1 could be sold to other series, because many other series use 18 inch rims.jjn9128 wrote: ↑12 May 2021, 11:52F2 is only using 18s because F1 is going to change, however F2 tyres are the old F1 widths - 275mm front and 325mm rear treads, with a 705mm inflated tyre diameter.

It's purely marketing. Then a little blag about sidewall movement/making simulation easier.
I wonder how the hot air will be directed and vented after exiting the brake discs, knowing that it must exit from the inside face of the drum in 2022...jjn9128 wrote: ↑11 May 2021, 12:28The 18" is coming for a multitude of reasons. Lower profile = less aerodynamic movement = easier to simulate. Tyre suppliers want it to look more like their road product (I can only imagine for very stupid people, the sort who took up smoking because F1 cars were sponsored by tobacco companies).
The covers are to block the brake cooling flow - keeping the wake narrow. I imagine they might look better painted... but still.
You know I hated the idea when it was floated for marketing, but I just realised you could put a speed readout on the wheels for when the cars are chasing each other down the straights which would be fun...
I think the williams vents all of the rear brakes on the inside.Blackout wrote: ↑13 May 2021, 21:46

Well, today some cars seem to vent some of the rear brake air from the inside, but those drums are also quite obscure to me : P
