For those wondering, when turning your tires are not firmly planted to the ground. When at an angle (when wheel is turned) to the direction of travel, the tire still "slips" across the pavement in the original direction of travel, to a degree. It is the friction from this that causes a car to turn. Modern tires are designed to take this into consideration when designed. As a side note, when slip angle becomes too extreme, traction is lost.
Oh joy someone explaining momentum and how anything in the world actually interacts with objects SUCH AS YOUR FEET. Now I’d think your shoes would start to ‘slip’ if full sprinting and then try to make a very hard turn either you topple or skid depending on how fast you gain traction.
I have a theory... You know why they showing old videos, because owner of this channel is long gone from this channel and they are not playing money to him, that is case of 80% of old videos.. My theory..
All jokes aside, I'm just glad there are people out there R&Ding products like this for us consumers. You can't reinvent the wheel, but you sure as hell can try and make it as safe as humanly possible 👍 shout out to all my engineering home boys!
Tires deform while the car is turning. This effect is more common in racing since at higher speed much stronger forces affect the tire. And also that's why softer tires give car more grip, because they can deform more easily without loosing grip, which improves cornering. Hard tires on the other hand are more durable and better at handling higher maximum speed. I might be wrong, but that's how I understand this topic.
I just like how people 6-11 years ago we’re having actual conversations and being smart while people nowadays go there and be like “HeY yoUr cOmmEnt iS 10 YeArs Old, ArE u StiLl AlivE?”
You know the internet was small back then, 2 million+ views videos were considered viral. The internet hasnt changed, it just got bigger and- bigger = more dumb people.
At 0:13, the tire begins to slide, and leaves markings on the rolling belt, but then by 0:18 they disappear because the tire picks the rubber back up...
literally what happens when you actually properly load a tire. This isn't during "uncomfortably fast" cornering, this is during conering faster than you thought your car could.
Yeah i agree. I often corner fast enough to break the tire's limits and cause it to slip slightly. You can feel the sidewall changing shape while you do that, since my tires have high sidewalls
Thing about all that slip angle is it helps so much with grip. I experienced this just a week ago driving with snow tires on the front and low profile tires on the back (front wheel drive). I usually expect understeer from this car. Even though the rear had a wider contact patch the front was more pliant and had deeper tread on the varying road surface and before I knew it I was facing backwards. Luckily I managed to right it and carry on with no damage or anyone seeing!
@@RJW14 Dry and probably about 2-4•c as it was a sunny cold morning. I imagine if it was about 18•c and dry the rear tires would have been nice and warm and the front would have been too soft and I would have understeered. It was quite a tight corner, one that most people probably go around at 30-40mph but I was doing a bit more than that.
@theclivesinclair, Robert William Thompson of Stonehaven invented the pnumatic tyre which he patented in 1845, Thompsons tyre never made it into production due to costs but was further developed by John Dunlop. Thompson also invented the fountain pen, and the practice of detonating explosives by wire among many other things. The davidsons of Harley Davidson Motercycles were born a mere 40 miles south of Stonehaven just outside Aberlemno nr Brechin Angus. Just an interesting fact for you.
Any video that gets picked up by tHe aLgOriThM automatically becomes a cesspool of idiots just trying to get top comment. Not much that can be done I’m afraid.
@@ThePhobophile exactly. I miss the times when people made original funny comments. Now it’s filled with Fortnite kids posting godawful nobody jokes and chasing likes
f1 on previous decades, team makes their tyre lasts the whole race. imagine the stress of the current f1 tyres holding it with intense downforce that makes it 3x the weight of the car.
actually Pirelli F1 tires are created to behave like that . also teams can make tires last a race distance , but there's a mandatory tire compound change
For dummies like me. Slip angle: difference between where the wheel is pointing and where the wheel is traveling. Factors are : force (car weight, traction, pretty much any force you attempt to put through the tire.) And tire stiffness (construction and pressure) Knowing that you can use it as an indicator as to how much load or work a tire is doing. Running large slip angles make a tire more forgiving to harsh setups, tracks and driver inputs. It dampens forces. But it also deforms the contact patch, which reduces grip on smooth surfaces. Can be used to adjust the cornering yaw angle of the car. There's definitely more. What am I forgetting?
@purpleGoAhead You need to inflate to what the door sticker says. Tires are consistent enough for the door sticker to be accurate with the stock wheel size and tire specs, and they design it so you have the maximum fuel economy, maximum tire life and maximum grip. If you aren't running that pressure you ARE putting EVERYONE at risk.
Most people get recommended this video, but I actually found it the other day when I was learning about slip angle (four wheel drifting) in a sim racing game lol
Maybe you were like a sample for the algorithm, like "look this ordinary dude watched this old tire video, it must be hidden treasure" and then it got recommend to every one. Or just a thought I'm like 8.5/10 now
@philtripe just because your tire says 44psi that doesn't mean to fill them that high. if u read the tire it says for maximum payload capability then fill to that pressure. otherwise you are suppose to full the tires according to the vehicles recommendation,.
Not camber, toe. The camber doesn't appear to change at all. Camber basically just means that the chassis roll dials contact patch into the tyre and the conicalisation of a tyre creates the effect of a cone rolling around it's tip, generating a turning force towards the opposite side, whilst reducing the equivalent force generated on the opposite wheel.
@@ajwright5512 I mean yes, but also it is important to clarify that it only applies to the rear wheels, because on the front; When aligning or choosing your alignment, you set the static toe, meaning the toe° when the steering is at dead centre or 0°, and when the steering is centred you don't have any slip angle because slip angle requires lateral forces that you won't have unless you steer. But when you are at an steering point in which you generate a significant amount of lateral forces required to create slip angle, the toe that you set statically doesn't matter (except for the very few first degrees of steering rotation but the lateral forces aren't big enough to create slip angle yet), ackerman takes over and you will have (plus or minus a few degrees) the same toe regardless of what you set statically
@meleman0872 thats what the guys at the tire shop tell me...but i changed from the oem tires to a much better tire and oem tires require 28 psi and my truck feels like im driving on ice at that psi and the tires wear excessively and now i get over 40k out of my tires without ever having to rotate(rear wheel drive w/ a tire thats rated for 40k)
While playing Forza I would sometimes watch a replay with the camera pointed towards the wheels just to watch the sidewall flexing because I found it so interesting
@@vargasaidan7366 I think the original Motorsport had it and of course all of the ones that came after it. I'm almost certain Horizon would have kept it in the game
Not funny I didn't laugh. Your joke is so bad I would have preferred the joke went over my head and you gave up re-telling me the joke. To be honest this is a horrid attempt at trying to get a laugh out of me. Not a chuckle, not a hehe, not even a subtle burst of air out of my esophagus. Science says before you laugh your brain preps your face muscles but I didn't even feel the slightest twitch. 0/10 this joke is so bad I cannot believe anyone legally allowed you to be creative at all. The amount of brain power you must have put into that joke has the potential to power every house on Earth. Get a personality and learn how to make jokes, read a book. I'm not saying this to be funny I genuinely mean it on how this is just bottom barrel embarrassment at comedy. You've single handedly killed humor and every comedic act on the planet. I'm so disappointed that society has failed as a whole in being able to teach you how to be funny. Honestly if I put in all my power and time to try and make your joke funny it would require Einstein himself to build a device to strap me into so I can be connected to the energy of a billion stars to do it, and even then all that joke would get from people is a subtle scuff. You're lucky I still have the slightest of empathy for you after telling that joke otherwise I would have committed every war crime in the book just to prevent you from attempting any humor ever again. We should put that joke in text books so future generations can be wary of becoming such an absolute comedic failure. Im disappointed, hurt, and outright offended that my precious time has been wasted in my brain understanding that joke. In the time that took I was planning on helping kids who have been orphaned, but because of that you've waisted my time explaining the obscene integrity of your terrible attempt at comedy. Now those kids are suffering without meals and there's nobody to blame but you. I hope you're happy with what you have done and I truly hope you can move on and learn from this piss poor attempt
I am an engineer working at a car company - I had to unironically search this up to watch again because it's so interesting, after it got recommended to me the first time LOL
Generally a thicker sidewall means more slip angle when cornering, but other factors effect it like tyre pressure and sidewall stiffness, the biggest difference between an eco tyre compared to a sportier tyre apart from rubber compound is the stiffness of the sidewall. A stiffer sidewall won’t just limit slip angle but also tyre ‘roll over’ where a tyre can slip so much it wears the tyre edge and is nearly running on the sideway
Cheers. I made a upgrade to my car last year and want to share my findongs woth you. My goal was to have a more responding handling in my car. But it should be comfortable on the straights as well. So my rims have a width if 9.5inch The tire is 255 which is a slight stretch. The result is amazing. The initial steering response is almost immediate but falls flat when cornering in high speeds. The tire is the Fulda Sport Control 2 which is a soft tire with high grip and high comfort. So what I want to say is. The width of the rim has hige impact on the tire roll.
@valereydyachuk If it's stock you want to use the pressure the manufacturer claims. If you've put some serious suspension mods on the car, or aftermarket wheels and tires, then you'll have to experiment a bit. Sidewall PSI is still a no go.
I felt my sidewall doing this when I understeered in my V6 Charger taking a corner faster than I should've back when I was in high school, didn't crash it but was still terrifying, I drove that thing to its limits, it's no wonder the engine blew up on me
@@bobross6677 definitely feel like that's what happened because I didn't let it warm up, I let the Mustang warm up and I don't drive it as hard, I get on it occasionally but usually shifting gears and hearing a V8 is enough for me
Дааа как быстро время утекает, я помню тот ещё ютуб который не был заполонен дерьмом, когда были короткие, интересные и смешные видео, а не то что сейчас постановочный шлак, дешёвые пранки, и море море ссанины...
I'm a sim racer for over 20 years so I get this is recommended to me. I'm interested in slip angles, break traction points and so on. Apparently everyone is a sim racer. Good!
@cyberhendrix That's why I'm replacing all four ball joints on my I-beams. I still don't need it super-tight though because it's not designed to carve corners.
Fun, visual way to understand how tires actually work. They’re not just along for the ride - they’re what actually do the labor of pulling the car along, and the physics of it are bonkers. Most racing sims do not model the actual physics, but use statistical models from data collected in real life; it would be entirely too resource intensive to figure out tire physics in real time, and even tire makers may not have it all figured out. Video itself just shows a tire being pressed into a rolling road/dyno at speed and then turned. This is a tire that is powered - the axle is putting torque on the wheel and the tire is transferring that torque into the ground. When the wheel is turned, the tire wants to turn, and that turning force is deforming the whole face of the tire.
@valereydyachuk 300ci inline six running on gasoline. Behind that is an overdrive 4-speed manual gearbox. It's no miracle at all. 300s are known for lasting forever.
@@confus9d Fuck yes 4-speed in 2020. Modern cars are utter shite. Disposable pieces of clausterphobic plastic junk that won't last 10-15 years before they start falling apart around you. My next car purchase will be a Ford 4-door from the 1930s. Flathead V8 and 3-speed will remain. Hell I won't even put radial tires on the bitch. I will give it aircon and a nice radio though.
@@TestECull 👍🏼 I totally agree with you, modern cars won’t last as long as a manual 4 speed cars, Especially with tech so you cannot fix your new car, and that’s a really cool car for your new next purchases
@@LSM_OPTiX Yuuuup. I want a car that will outlive gasoline itself, then outlive the next two fuels it gets converted to run on and the person driving it. And I'm not gonna find that on a new car lot. I figure, if it's already lasted 90 years and is still driveable it's gonna last another 90 years. So fuckit. Gonna pick me up some classy flathead-powered rolling Art Deco! I won't even mod it very much. Air con, an FM radio, seatbelts, a cupholder, a 12v socket to charge my phone/dashcam off of and *maybe* a more modern carb with auto choke that's easier to get rebuild kits for. If it wants to overheat I'll prolly put electric water pumps on it but if it stays cool as-is I won't mess with that. Won't even put radial tires on it. Coker sells bias tires in the size it calls for and tehy only want about $150 or so per tire, which is cheaper than what you pay per-tire for a modern car's tires!
@@TestECull ayyy not bad at all! Sounds pretty genius, Just might wanna fix the engine and over all fix everything that’s wrong with it, I’m looking forward on buying a 1993 Supra but I can’t because of my age, But over all hope you manage to do that, If that happens you should make a video of it and I’ll be happy to watch
I could be working on getting homework done for my drivers license, I could be sleeping cause I have to get up in 8 hours. But no I’m sitting here watching a tire roll around from 13 years ago
People 10 years ago: Let's help the others who couldn't see when it happened People now: Is that a meme? Is that a reference? Wow RU-vid recommendation.
For anyone wondering what’s happening: All cars tires when going around a corner will slip a tiny bit (a few percent). This video demonstrates that by having a treadmill constantly going one way, and a tire turning. The reason why the would even make a machine to study this slip is to develop new tire construction, because deformation like you see in the video helps the tire retain its static friction coefficient, rather than slip 2% and then go into kinetic friction (kinetic friction is the friction between a sliding thing and a surface, and it’s much lower than static friction). Tire slip in itself isn’t tire deformation, it’s the tire slipping/sliding a tiny amount when turning (fighting the cars intertia). Tire deformation is to make sure that once the car slides 2%, the sliding doesn’t get worse and worse very quickly.
I always wondered how wind could push your car even though your steering wheel remains straight. And why you need to fight the wind by steering into it, yet you're still going straight. It's because when the wind pushes on your car, it's also bending your tire sidewalls due to the force of it, and that changes the way the tire contacts the road and causes your car to be "pushed" by the wind
Because some vehicles have specific applications. Pickup trucks are designed to tow, haul and off road. Pickup trucks are designed to be as tough as they can possibly be. They are not designed to go around corners quickly. You wouldn't use a computer to cook dinner, would you? You wouldn't use a circular saw to open a letter, right? So why ask a pickup truck to do a sports car's job?
