Why F1 Wheels AREN'T STRAIGHT | feat

[@bobbyrandom5595]

As an engineer and a budding sim-racer, I think this is my favorite video of yours so far. It perfectly toes the line of technical explanation and real meaning for the adjustments without becoming an hour long tuning course. Great stuff Scott! I've got some new things to think about while tweaking my car in ACC. Speaking of which, please show ACC some more love on Trophi! Especially the Huracan Evo 2 😉

[@alecmillea4539]

So glad to see a collaboration between my two favourite motorsports content creators! I’d love to see more technical explanations from the two of you! Keep up the great work guys!

[@BPBomber]

Glad you guys crossed over with Brraakkee or however he spells it. He seems like a great guy with a ton of technical and analytical knowledge of F1 cars. I’d love to see him be successful in this

[@nicholascrow8133]

Lower tyre pressure and the resulting extra tyre flex also helps (and hinders, depending on the situation) in building tyre temp

[@johnbarker5009]

This is a particularly good video, a topic I don't think some of more recent F1 fans understand. All those mechanics swarming over the car during practice and qualifying have a lot more to do than placing the cooling fans and wiping the car with a polishing cloth. I think there's a tendency to think they drive nearly the same car at all times, or maybe they set it all up at the shop using simulator data and just run it that way. That's never going to be the case. The simulator isn't perfect, it's just close. It can't know exactly how the pavement aged over the last year, fully incorporate any pavement heaving or new patches that occurred since their last visit, or deal with normal variations in temperature, humidity, or the likelihood of rain.

[@stanbest3743]

They have reverse Ackerman front geometry because of weight transfer meaning the outside wheel can stand more slip angle. They aren't designed to be driven slowly 😊

Great collab, I have been watching his channel from time to time :).

[@chrismoody1342]

I look at this as a Forza sim player. The whole tuning the suspension was paramount to building a great car. You wanted to build as much mechanical grip as possible without applying to much downforce slowing the car. I’d spend hours watching the heating across the tires when at track speeds. Next was how compliant the suspension was. Getting the bump rate was pretty straight forward but getting the rebound rate was much more complicated. When you hit the sweet spot the car would be a pleasure to drive.

[@underSTATEDexcellence]

Funny but long story My weekend warriors suspension is completely adjustable (ride height, camber, caster, toe) and I spent a good month every weekend dialing it in. Every time my neighbor would come out and say “you broke something again”, even after I clearly explained it to him. And he wasn’t joking or being pedantic he literally couldn’t understand it. Flew straight over his head every time. The chick across the street understood perfectly, even his wife got it. He just doesn’t get cars and how they can be your passion. He would tell me “You must hate having to do that” when all I hated was him…. Lol

[@geemy9675]

quick math 800kg*5g/4 each tire with contact patch the size of your palm is actually pushing the road ~1000kg towards the outside of the turn (and same reactive force tranfered to the car towards the inside)!

[@user-tn1vc1xz5d]

Speaking of high cars.....I drove a Vauxhall Zafira VXR around Thruxton once. The front tyres deserved a mention in dispatches.

[@vincecarlo]

This Explains it Very Clearly

[@SkunksterPlaysPoorly]

This was a great explanation of the various suspension settings on these cars. I’ve always wondered how they are able to get it set back up correctly when a driver destroys a corner and all of those parts need to be replaced. It’s not like you ever see them doing an alignment in the garage.

[@tonywright8294]

Toe in and toe out increases grip due to the scrubbing effect. The maximum grip occurs just before the tyre slips it’s known as the slip stick effect .

[@nutsmcflurry3737]

Scott, what about a series about the pitfalls and idiosyncrasies of the current F1 tracks? After this weekend I imagine there will be a lot of things to talk about from LosVegas.

[@rolandotillit2867]

Toe has an aero effect. Toe in increases the wake on the inboard part of the wheel, toe out reduces it. Of course for the effects to be significant you have to run like 5 degrees of toe, not realistic or practical. Outwash inboard of the wheel does the same thing as geometric toe out from an aerodynamic sense.

[@420_laundry]

as someone that learned skiing on straight planks.... That sounds like the difference between those old old straight skis compared to carving-skis.

[@wyskass861]

Anyone can change the toe settings in their own car and experience the effect themselves. Quicker turn in or stability vs tire wear. Of course camber and caster. Rather than spending thousands on mods, a simple wheel alignment adjustment can do wonders for performance. Unless you go nuts with it and make everything worse.

[@matthewschreiner2039]

Scott, I love your technological insights. My father introduced me to motorsport as a young child. However, he was a romantic and a bit halcyon about the grand prix he attended. I am always interested how cars work and not necessarily how good the driver is.

[@guttsu]

Man you could've easily just made a video about the toe-in/out and covered the title. But this was really in-depth and really interesting, thanks!

[@HBrooks]

one thing the sims/games could do would be to better represent graphically in the settings window, how any settings would actually affect the car. the amount of camber represented graphically such as in this video would be a great help with new drivers/players

[@flexinclouds]

Forza motorsports & horizon 5 are really good with the depth & realism of the tuning. But they just give a description iirc. A diagram/picture should definitely be included for those not already familiar with all of it

[@iplayeddsharpminor]

Love these videos and perfect timing. Still play Grand Prix 4 which helped me learn so many setup best practices before I even really understood the concepts behind them. Looking to finally upgrade to newer sims soon and many have additional things like pressure and camber to contend with so this will be going into the favourites!

I play 2 mobile tacing sims and yhe drift focused one has tire wer simulation, some setups definitely wear lower than others. Good thing they added time attack mode recently I can test these parameters there.

[@ljhamilt]

Common misconception in here about the effect of camber on contact patch area. Camber doesn't affect TOTAL contact patch area. Contact patch area is simply a function of tire pressure and load (weight). So a tire inflated to 20 psi supporting a 400 lb load will have a contact patch area of 20 square inches regardless of camber. Camber affects the SHAPE of the contact patch and therefore the distribution of stresses within the contact patch which can have a large effect on grip. Otherwise brilliant presentation!

[@The_ZeroLine]

brrrake just told us that AM’s performance drop was due to the flexi wing TD, but then they reverted back to their old aero package and got fast again. Whoops.

[@DaredevilGG]

Interestingly, camber, caster and toe is actually something that all road cars have built in as well, though it's obviously not for performance, but to manage the wear of tyres, and they do have to be adjusted every now and again, and tyre pressures is obviously something as well, but that is more common knowledge than the others

[@M0UAW_IO83]

It is also for handling and performance as well as tyre wear, road car setup is a compromise between many factors, if it were set wrong you'd pretty soon be complaining about fuel economy, lack of manouverability, heavy steering and picking bits of your car up off the side of the road after you'd lost control and smashed it up on a corner.

[@mohammadsattar5488]

Just as a train has its steel wheels set on an angle on the railroad tracks so it will go straight but if you put the wheels square on the they will go into themselves

[@biggallcaps]

It is honestly a shame how little wiggle room for adjustments related to the tires the teams actually have. With how tire development has progressed to try to provide maximum durability and consistency, it really has killed the unpredictability of tire strategy during the races.

[@nvcnc]

In part this is a safety issue. Too low tire pressures can be faster and yet cause damage to the tires leading to failures.

[@NBSV1]

That’s what you get with a single make in a high level series. There’s no competition so tire makers do what they want and blame the teams if there’s a problem. Rather than design a tire that works with what the teams want they’re designing tires for what they want and making the teams try to figure it out.

[@8alakai8]

even your normal car the wheels dont all point strait forword with front wheel drive they point slitly to the outside to compensate voor the power on the wheels that will pull them inward

[@nickcook7408]

Not true - look up the target parameters for any fwd car, you’ll see they always toe in. Manufacturers prioritise customer desire over engineering knowledge.

[@hamadwaleed5452]

This is mega it helped me alot and please we want more car setup videos please ......... thanks🙏🐐

[@alundrasrt]

First I thought that the diagonal tire contact is longer that shorter straight contact but I know it's deeper than that too.

[@Gdad-20]

We use to run our back wheel out of line, Toe to the right on speedway bikes, to keep the bike straight, when conering/keep the bike running in line...... 👍🏁🇬🇧 Although on speedway, we only turn left! Lol 😂

[@tonyloosa9500]

What if there was a way for your wheels to automatically adjust the camber angle to maximize grip, improving acceleration, breaking, corning all while extending tire life and improving fuel economy?

[@dsdy1205]

That's active suspension

[@12th.jahlil]

That level of active adjustment isnt even made, itd most likely weight alot though, it might be slower then manually setting it up

[@Noreceipts400]

@@dsdy1205 I dont think that impacts camber. Just damping and spring rate i believe

The total weight added to the car would be very minor. The angle adjustment would be calculated by and onboard computer weighing less than a smart phone. I'm the patent owner this concept.@@12th.jahlil

[@mirnivoznik8536]

Finally we talk about settings. People only praise drivers and know NOTHING about how the car works and that this is actually a team sport. All of these settings (that you can easily get wrong) play a massive role that can decide a race (by tyre wear, slow-speed corners, grip ...). And yet even the F1 commentators only say "Lewis wasn't feeling it today".

[@audistik1199]

Why are shocks never discussed? In my racing experience I found the shocks have a profound effect on handling.

[@Khaynizzle7]

I still do not understand how to out gives you more bite when the weight is going to be over the outside wheel more.

They would go faster if they could get the wheels straight. A common wheel alignment for around £100 would fix it for most cars.

[@Robert-cu9bm]

With tyre pressures @ 20psi how do they get the responsiveness out of the steering? Especially with the old cars running 15 inch wheels.

[@Dyson_Cyberdynesystems]

Because contact area has nothing to do with friction. The contact area has to do with the structural integrity as well as wear and tear on tires. People never distinguish the physics involved when talking about "traction"..

[@Robert-cu9bm]

@@Dyson_Cyberdynesystems I'm not talking about the contract area. However the contact area is directly responsible for how much friction there is. Bigger contact area equals more friction. I'm talking about low pressures allow the rim move. Lower the pressures in any vehicle and the steering becomes less responsive.

[@Dyson_Cyberdynesystems]

@@Robert-cu9bm I mean. I'm not giving you an opinion. Friction is completely independent from contact area. It is a product of the friction coefficient of two materials and the normal force applied to the contact plane. Tires would be less "responsive" because the tire structure collapses under lateral forces. You can counter for that with structural sidewall reinforcement or lower profile tires..

[@Robert-cu9bm]

@@Dyson_Cyberdynesystems we're taking about contact area and friction on cars. The More contact area on a car the more friction you get. F1 must have really stiff sidewalls then.

[@maozedowner5915]

Hi, I identify as a F1 wheel.

So this is why Ferrari can have a great pace but burn up tires. They sacrificed tire longevity for higher grip to keep up where red bull needs less camber to keep the same grip with their overall better design, aero and setup.

Is the DAS the "magic" Ham was mentioning after he crashed soon after warming his tires?

[@mr0sparkles4682]

No, he was referring to a brake bias setting. The "brake magic" setting shifts more brake pressure to the front. This allows the front brakes to generate more heat and warm the front tires better. He accidentally turned it back on and cause the front tires to lock up.

[@StingrayOfficial]
