Not true, an increase in contact patch area increases (not linearly) the coefficient of friction. This can also be seen when lowering the tyre pressure , it has a direct relation to the increase of contact patch area and therefore also the coefficient of friction. Not only this but increasing the tyre width also increasing the tyres cornering stiffness which contributes to its lateral grip capability
I READ THIS IN A WELL KNOWN MOTORCYCLE MAGAZINE BACK IN THE MID 70s Motorcycle slick tires really did happen by accident similar to the Ferrari story. Back in the late 60s early 70s team Harley-Davidson arrived late to a road-race and all they had was factory slick tires and no time to cut in thread patterns which was the norm. So they had no choice but to go out and try to qualify on slicks and the team mechanics all thinking it was going to be a disaster. Well not only did they qualify, but they danced circles around their competition that was always faster than Harley. Back in the day, in order to get the number one AMA national title you had to race flat-track, and road-race. Harley was great at Flat Track but not so fast in Road Racing. And for a while the slicks allowed them to podium in road races.
Very cool video, but there is one thing I do not agree with. At about 2:30, you said Formula 1 car have wings because they generate down force, which makes the tire shape better in the asphalt. Then you said this was important because the bigger the contact area, the bigger the grip. However i disagree with you. According to physics, the grip equation is: Grip = K * weight, where k is a constant. F1 car have wings because it makes the car weight heaver, and then have more grip. In the equation, we can see that the grip does not depend on the surface area. But then you might wonder why race cars have wide tires. This is simply so that the tire does not collapse while the car is accelerating. This happens because if the tire has a bigger surface area, the engine torque will be distributed on a bigger surface, making the tire not to explode.
Again since friction is the for no slip condition, I disagree with you and also to be noted though in school textbooks its told k*normal force and does not depend on area, actually dependence on contact area is based on the context, you can check friction models if you feel I am wrong.
Why don't we have to invent a new tyre, that could deform into slick tyre when asphalt is try, and deform into grooved tyre when it is rainy, may be that led to less consumption of time, is it possible🤔
It’s actually quite simple why slicks weren’t used in the 50s. Summer wasn’t invented yet.
As for physics, grip itself is the same for any area. It's about how a tire and its thread deforms

Naska is one of the few people who can teach you something you already know in a way that is just as interesting as if you never knew it
I already had a decent idea of why they use slicks. But this video was still very insightful and super interesting!

Very great work 👏🏼 man
Very nicely done. Good information and well researched.
really love you vids bro, have so much knowledge based on science, keep it up always !!
It's the same what happens to your skin (specially your hands) when it's wet. If you notice they get wrinklier so it can have better grips.
🙏thx man, very interesting video 🙌

Nice!!!
If they want to make Grand Prix more exciting, they just have to replace F1s with Legend cars 🤪
Naska we want more race when will the racing video be coming????
