I wonder why they didn't remain the the full disk sidewalls that the CFD model and I think the wind tunnel miniature showed.MtthsMlw wrote: ↑14 Dec 2021, 09:46With aero covers

It would look cool if they went for smaller fronts with tall rear, just aesthetics no considerations on balance.
I think they explained it in the more recent video of the new cars, something about the flow stayed better attached like this.mzso wrote: ↑14 Dec 2021, 14:54I wonder why they didn't remain the the full disk sidewalls that the CFD model and I think the wind tunnel miniature showed.MtthsMlw wrote: ↑14 Dec 2021, 09:46With aero covers

Probably because the smooth surface meant the front tyres "sailed" i.e. created a sideforce which unsettles the driver.mzso wrote: ↑14 Dec 2021, 14:54I wonder why they didn't remain the the full disk sidewalls that the CFD model and I think the wind tunnel miniature showed.MtthsMlw wrote: ↑14 Dec 2021, 09:46With aero covers

Could be, until a couple of years ago I raced Time-trials and disc wheels were commonplace (on rear wheels) and above particular speeds there was a definite ‘sail-force’ created.jjn9128 wrote: ↑14 Dec 2021, 18:24Probably because the smooth surface meant the front tyres "sailed" i.e. created a sideforce which unsettles the driver.mzso wrote: ↑14 Dec 2021, 14:54I wonder why they didn't remain the the full disk sidewalls that the CFD model and I think the wind tunnel miniature showed.MtthsMlw wrote: ↑14 Dec 2021, 09:46With aero covers

They are crazy tall! The back looks ok but the front just looks odd.mclaren111 wrote: ↑15 Dec 2021, 11:19https://www.motorsportweek.com/2021/12/ ... nch-tyres/
Comparison of 13" vs 18".... These things are Huge...

Isola explained that revisions were required for the initial wheel cover designs for the 18-inch tyres to ensure they remained balance, and that pit crews could easily remove the tyres from the car.
“The first version of the rim cover was very close to the rim, and we had two problems. One was for the mechanics in the pit stops, because they need to put their fingers in and take the tyres off, and with the wheel cover it was not possible, so they had to modify it.
“The second was we couldn’t add the balanced weight on the outside. That’s why if you see the latest version of the wheel cover, there is a shape that is covering the rim, but then you have a step closer to the rim that is useful for the mechanics to take the tyre and for us to balance the weight.
“With this final version, we can balance the tyre when it’s fitted with the wheel and the wheel cover. Otherwise, if you add the wheel cover after balancing, it can be a problem.”
That's the answer, thank youSchippke wrote: ↑15 Dec 2021, 11:50This might also form part of it too:
