What is up with tire grip? Why do wider tires have more grip? The answer is not what you think. Does the contact patch area matter? Why is it important to understand that tires are viscoelastic?
Lets figure out the Dark secrets of tire grip.

Damn, as an engineer I feel ashamed for not questioning the theories used on those videos mentioned earlier now. That's very enlightening overall, love your videos, keep educating us please.

My thoughts exactly. Although I'm no longer working in engineering, that was what I studied and F=uN was my explanation for tyre grip. I'm glad I watched this before buying a spring balance and setting up an experiment to make myself look daft. Just goes to prove that "a little bit of knowledge can be a dangerous thing".

Speaking as a former tyre test development rider, it also needs to be pointed out that upping tyre sizes, even from the same manufacturer & model, rarely gives more grip at the contact patch is defined by the tyres vertical stiffness, lateral stiffness, & rim produced profile. Often 2 tyre sizes have differing vertical &/or lateral stiffness, & the larger tyre may well have a smaller contact patch area on the same rim, as tyres can be fitted generally on approx 5 rims sizes and their vertical/lateral stiffness, contact patches upright, & leant over, profile, grip, & feedback will be different on each rim. Shape is everything

@DumbledoreMcCracken
@DumbledoreMcCracken 3 года назад
Many "engineers" think the equations they learned dictate the behavior of real physical systems. Those equations are only applicable to a narrow set of conditions, and nature is free to generate data that is in disagreement with the (simple) equations, given the limited applicability of the equations. My hypothesis is that Germans are taught that electrical systems behave as per the aggregate of manufacturer's specification, and design fragile systems based on the inability to imagine corner cases. That's the only way I can imagine the stark difference between German electrical systems and Japanese electrical systems.

I'm reading Motorcycle Dynamics at this exact moment! As a tire nerd/material scientist/chemist/mechanical engineer/former racer, thank you SO MUCH for making this video. Tires are so under appreciated, they're all just black and round right? This video is already in depth, but only scratches the surface of the complexity. Could have added (and probably way too technical) the Loss Modulus and Storage Modulus based on temperature (such as a DMA graph). Which is a discussion on glass transition temperature/rubbery plateau/flow region to demonstrate exactly why operating temperatures are so critical to tire operation, tire warmup, and over-heating. It would also be cool to see a comparison of a 190 rear on a 5.5" and 6" rear wheel. U vs V profile on the wheel, and contact patch at lean angle vs straight line stability based on that profile. Such a great video.

Ohhhh man I fucking love the Carrol Smith books. Have devoured all of them. Holy fuck you actually read Miliken? Clearly you are my type of person. I've also read Gillespie. If you get a chance read "Race Car Engineering" by Paul Van Valkenburgh. I may have misspelled it. His books are very similar to Carrol Smith's books, but it's interesting to see the same information from someone else's opinion. Got a new subscriber by the way

@andyjonathan2486
@andyjonathan2486 Год назад
Great video and excellent explanations. For SCCA autocross, I found that if went with too wide of a tire, it would generate less grip because for lightweight cars, the tire temperature would not increase enough during a 50-60 second run. The pressure at the contact patch decreased too much, in which hysteric deformation of the rubber into the tarmac asperities was reduced. Tire dynamics is indeed a very complicated topic. My head was spinning when I studied the brush model, dugoff model, and ‘magic’ tire formula back in school.

No first year engineering student can make any statement on the validity of this video. The concepts here just begin to get into polymer science. Viscoelastic materials can be thought of as a dash pot and spring combination. I guarantee you that no undergrad ME has a scientific understanding of this topic (viscoelastic materials was a 500 level class in my Master's program). Please see the references Mike has listed.

My conclusion- it’s a complicated business and I’m really glad we can benefit from the research and testing those top brand manufacturers put in.
