I don't think you can draw any meaningful conclusion based on that image. The difference in head height could be anything from 0 to 10 cm's from those two images. It surprises me that you signal out a single item in the argument out of the five I listed when any significant advantage of going to that big a tire diameter has yet to be communicated at all. |

the drivers seemed more then capable of managing the larger front wings that they couldn't properly see the end plates of...any reason to think they wont be able to manage their cars dimensions with the larger tires with the aero bit over them?

Why are these five factors important?
- Visibility. - Weight. - Lower centre of gravity. - Less drag. - Less aero distrubance. |

IMHO the bigger/wider tyres look awesome and the smaller/narrower ones look lame and that is a significant (indeed, to me, decisive) advantage.

I know you are passionate about this topic. You have worked to make this a true and calm discussion. And I think it has been. And please understand that I disagree with the idea and this is not about you. Of course there is both and upper and lower limit on how wide or tall the tires should be. But I don't believe radically changing them (particularly to make the diameter much smaller or to reduce the width to reduce spray and increase traction in the wet) are good ideas at all. Or any of the other points you make. At least enough to support a change. The topic has been dead for months and I really just don't see anyone who supports this idea either here or in F1 in general. When you posted earlier this week, I saw it and thought... "Nope, not gonna engage on this again!" even when I was thinking all of the comments I posted above. Sadly, V8 Fireworks post sucked me back in. I should have just not posted. I think I will go back into hibernation on this topic until I think there is something I can add beyond what I have already said. This is basically the same conclusion I had back in Oct. when we had a number of back and forth on this. Richard |

I think the width is the same as before, so F2 uses 245mm/725mm R18" front and 325mm/725mm R18" rear, i.e., 20% narrower than what F1 will use. Like I said those cars are 1.9m wide, which doesn't look too bad. F1 could use the same car width and tyre sizes as F2 if they wanted, it wouldn't be a big deal... The cars would have ~20% less mechanical grip (and therefore total, as aero grip is just a multiplier) of course. They would corner slower, but go faster on the straights with the lower air resistance of the narrower tyres. The car concept of the 2022 F1 car isn't that different than the F2 car apart from having that 10cm of extra width and the F1 car being much, much longer. I like the rears, but feel the fronts in F1 are too wide and look kinda silly. Last edited by V8 Fireworks; 12 Feb 2022 at 01:12. |

If these F1 cars weren't such enormous barges, smaller wheels would look perfectly proportionate. I didn't hear anyone complain about the small wheels and tires on the 2021 cars though. As V8 Fireworks already said, the teams didn't want the further reduction in wheelbase the FIA had proposed. Maybe with the drop of the MGU-H in 2026, we will see another effort to decrease the size (and weight) of the cars. |

But I'll be a good sport. Based on the helmet size (awfully blunt way of doing it but okay) compared to the vertical distance from the top of the visor to the bottom of the floor. If the LMP top of the visor is 90cm above the car floor than based on the above two image the one in the F1 car is 82cm, so 8cm lower. This also still leaves the variable of the ride height of the car. If we assume equal ride height for the 2022 cars compared to an LMP than a LMP's drivers eyes are 8cm higher than in an F1 car. Assuming the difference between the height of the wake deflector on the F1 car and the fenders on an LMP is smaller than 8cm and the tire wall is equally high (which I suspect on a F1 car is actually higher, with a total front diameter 710mm vs 690mm on the LMP), the conclusion would be that purely based on height it will be easier to see the apex in a LMP. Of course, as you said, in the LMP you have the A-pillars and cleanness of the windscreen to consider. But I agree, I think we are taking this part of the discussion a bit too far... Quote:

Front rims: 15x8.5" Rear rims: 15x9.5" (Lotus 43 sizes, 49 may be wider) Front rims: 15"x9.65" Rear rims: 15"x11.5" (Honda RA273 rim sizes) Source: http://srmz.net/index.php?showtopic=4952 Therefore 13" wheels with high profile tyres being regulated in Formula One was surely arbitrary and of no real engineering basis? I think the rear wheels were restricted to 13" first, as teams still had a choice of 15" fronts in the early 80's. Why stick to 13" when USAC allowed 15" to the present day with no issue? 13" is so arbitrary, adopting 18" is perfectly fine... The only drawback is the FIA increasing the total tyre diameter as well, which is silly. 18" wheels with 680mm tyres (so only +10mm instead of +55mm) look perfectly ok: Last edited by V8 Fireworks; 12 Feb 2022 at 18:36. |

13" wheels were originally introduced to limit the size of the brakes, as most of the overtaking occurred under braking and the longer the distance the more opportunity to overtake. It is also the reason that F1 brakes are not allowed to be boosted. Then somebody introduced carbon fibre brake discs, and these were just allowed to continue with no thought to what they were doing to the racing.
F1, what would you expect, certainly not continuity of thought. |

Here's a picture that compares the 13'' to the 18'' (and this is without the wake deflector): See how much wider the rears actually look on the smaller diameter? They would nut be very dissimilar to a 15-inch indycar tyre. Just a slightly larger 16-inch wheel and a slightly lower side wall within roughly the same diameter. Since 2016 the wheel/tyre combo gained ~16.5kg due to the extra width in 2017 and another 14kg due the larger diameter wheels and tyres in 2022. So in total the wheel/tyre combo got more than 30kg heavier. All rotational unsprung mass. If in 2026 we drop the MGU-H and we then do get the originally planned addition 20cm reduction in wheelbase on the current 10cm reduction (or perhaps even a bit more), we could go to a smaller diameter again which would still be nicely in proportion to the then smaller car. I could then imagine the following size: Front 265/670/16 Rear 365/670/16 For reference: 2016: Front 245/670/13 Rear 325/670/13 2022: Front 305/720/18 Rear 405/720/18 That tyre/wheel combo would weight about 15kg more on all corners combined than the 2016 combo, but 15.5kg less than the 2022 combo. You'd have: - The same tire wall height of the 2022 cars. - Proper visibility - Wheel size still nicely in proportion to the then smaller cars. - Less aquaplaning - Less spray - Less (unsprung) (rotation) mass. - Less drag - Less aero interference - 8cm wider opening leading to the venturi tunnels.

These are Super Formula cars. At front: 270/620/R13 and rear: 360/620/R13 they don't have extremely wide tires. Still they look like proper wide open-wheel class tires. Why? Because they are not ridiculously tall like the 2022 F1 tires and the cars are not barges like current F1 cars. This is the average wheelbase and length of an F1 car: 3.660mm and 5.695mm This is from the Super Formula car: 3.115mm and 5.233mm Super Formula has logically specced tires that makes technical sense. F1 well..... |

- The same tire wall height of the 2022 cars. This not what I'm suggesting, this is the change F1 and Pirelli wanted. - Proper visibility. I won't explain again cause it bad for my mood. - Wheel size still nicely in proportion to the then smaller cars. Important to the 18-inch crowd apparently (allthough to me they look too big even on the huge F1 cars we have today). - Less aquaplaning Safer, less rounds behind the safety car and more racing on a wet race day. - Less spray Agreed apparently - Less (unsprung) (rotation) mass. Improves acceleration (less fuel needed= lighter cars), grip (faster cars, need less downforce= less drag=less fuel = lighter cars) and better handling/more fun to drive. - Less drag less fuel needed=lighter cars - Less aero interference cleaner air to the following car=better following= better racing and better lift to drag= less fuel=lighter cars - 8cm wider opening leading to the venturi tunnels. better lift to drag= less fuel= lighter cars In aviation if an airplane is 15% heavier than it needs to be and it's engine 7x more expensive than necessary, any investor would laugh you out the door. in F1 we say it looks good and make excuses why it is a good design. |

I don't see the analogy. An airplane designed to carry people over a long distance and is built to one set of parameters. If a car can be designed, built and sold for less than £8k in the UK - then why don't we laugh every other heavier, more expensive car out of the door? Because F1 is not about building the lightest car to move people around in - it is about creating a formula within which competitors race. There are many things about F1 that could be done to make cheaper, lighter cars to race in. Why don't they just use F4 regulations? From the outset, it seems like the case to go back to smaller wheels and tyres is based on a dislike for the 18" wheels, and has no real benefits to F1. |

None of those factors is true of F1. The commercial return F1 teams get depends in large part on the appeal of the cars to fans with a wide range of preferences, from the highly technical (you) to the purely aesthetic (me). It's never been purely about building a car with bleeding edge technology. Personally as well anything that makes the cars harder to drive is good. Driver can't see the apex? Great! I also agree with the observation above that if a WEC or IMSA prototype driver can manage in the dark, in the rain, for three hours at a time, on four hours sleep, in a car not set up for them, with a greasy windshield and while constantly lapping slower cars, then it's not obvious to me why we should give an F1 driver seeing over the big front tyre even the slightest consideration. |

Current F1 cars are ~110kg heavier than they need be to fulfil the requirement of being the premier racing class, but because the manufacturers like greenwashing and F1 let's teenagers in fan survey's and the marketing department at Pirelli determine the proper wheel size, we are now stuck with what we have. Maybe they don't want light F1 cars any more. Because then the transition to battery powered electric cars would be such big disappointment. We'll see in 2026, where the weight will be going. I hope for sensible wheels sizes and sub 700kg, we'll see. Quote:
Perhaps F1 should abandon this class completely, slap "F1, the pinnacle of motorsport" on the windscreen at truckracing and be done. You know, they are low downforce (good), high drag (good), quite a handful to drive (excellent), huge wheels and tyres (looks so good). Quote:
To further expand, the 30.5kg change from the two wheel spec changes between 2016 and 2022 along with the change in diameter means in accelerations terms, they've added ~66kg equivalent of none rotating mass to the car. Quote:
https://www.racefans.net/2022/02/14/...nd-up-14-02-5/ This is a quote from Norris: “For certain tracks, it might be extremely different like Singapore or Monaco. One of my friends who’s in F2 said that they have to put cones on top of the barriers in places because the barriers were lower than the new tyres that we have, and that they can’t actually see where the barrier is, because the car looks higher than the barriers. We’ll have to get used to the size of it, the front wing and how big that is and so on.” So they are putting cones on top of barriers because the wheels obscure the view to the barriers they need to navigate. Again this is without the 5-7cm wake deflectors that F2 cars are not running. To further illustrate. A driver sits about 1.7m from the wake deflector. That means a 5-7cm height of the wake deflector will obscure an addition 50-70cm height at a barrier 17m away. Compared to 2021 wheels it's even 100 to 120cm. I know you guys think it's all fine when the wheels block your view on what you are supposed to navigate. To me it's utter nonsense. I think the chances that we are back to smaller diameter tires by 2026, are above 70%. |

I agree with you about the cars being too big and heavy and also take your point about smaller wheels having the same aesthetic impact when the cars themselves are smaller. We have big heavy wheels now because the cars are big and heavy, which makes the cars bigger and heavier still. That is an escalator I would like F1 to step off.

Are these 'too big and heavy' F1 cars the ones that were setting lap record times at 12 of the circuits on the calendar in the last two seasons?
I assume that they don't fulfil the basic requirement of being the fastest racing cars on the planet? |

That’s a tribute to aero and powertrain engineering. The cars are awesome, but they are also much larger than previous generations of F1. You may well not mind that or think it a problem. Personally I’d rather they achieved their ‘fastest car on the planet’ title with less weight, shorter wheelbase … and big wide tyres
