Looks great!!

The car just looks silly with wheels and tyres that big.

I think it looks great, and once you get used to it you may think the 13" wheels look really strange, just as F1 before halo now looks really strange.

As part of Liberty's Americanisation of F1, wheels will get bigger and shinier. The aim to get something road relevant by 2030. Something like this:

As 2019 starts I'm thinking more about this. The total amount of deflection on current F1 setups is not insignificant but as has been stated, it's primarily sidewall flex. How much change are we really going to see? LMP1 suspension seems to offer a similar amount of mechanical movement to current F1 but offers less sidewall deflection.
Will we see extra development in wheel designs since the metal part is going to make up a larger part of the unsprung and rotating weight?

The sidewall flex of the current tires limits the value of further increases in suspension stiffness to achieve constant ride height and pitch. 'Better' tires will allow the engineers to go to bone-shaker levels of suspension movement in search of downforce.

Those are probably just to transport the car

There's also this:
Pirelli: removing blankets bigger change than tyre size

I think it looks better than the ridiculous balloons we have today.

also, I think that any F1 teams that have close ties with any series that run 18 wheels already will have an initial advantage when they come in. *cough* Ferrari *cough*

[FPV GTHO]

Don't they test with the HALO?

What will fill the interiors? F1 abhors a void. Taller uprights. Larger diameter brake discs. More complex ductwork. The suspension arms could he moved up higher. The wheel diameter change alone should allow for 2.5"/6.4cm higher upper arms.

The outboard suspension & steering pivots could move further inside the wheel without restricting steering lock. Moving the kingpin axis further outboard--I dont know if this would be advantageous in this context.

I really appreciate the proportions of this car.
Looks much more like a racecar than the freaking limos F1 cars have become ....

[FrukostScones]

looks actually quite nice on this F2 mule or whatever it is.

yes will they allow bigger discs? They're limited at the moment, for some reason, if they leave them at 278mm that's a huge gap to flow air through.

Not a fan of big wheels. They look like sh!t on that lotus from a few years back. The wheels on the F2 car posted above don't look so bad tho. There's a Ferrari pic above, and looks to be the same amount of sh!t with the lotus. I think the wheels on WEC cars look like utter sh!t too.

I don't think bigger discs would provide any benefit, AFAIK braking force has been limited by the tyre grip for a long time now.
I've said this before, I expect them to go for these "semi-closed" designs like LMP1 and Indycar:


From my little aerodynamic knowledge, I guess this helps control turbulence a lot. What remains to be seen is if they're gonna use all that volume for air or not, I'm not sure if having more air to be compressed is a good thing or not.

bigger discs would improve braking control by needing less force, i saw 175kg quoted recently for current F1 pedal force! When you're near maximum effort it's harder to modulate muscle contraction, and of course that's exactly what they have to do as the downforce fades away with the car slowing.

But it's interesting what you show about filled-in spokes area. It might be a bit different in F1 with the floor and tea tray and outwash, my bet is they'll have to bring in some more rules about the aero side of them, if they want to keep the wake narrow, and perhaps they'll go for those filled-in areas
