14:18 "handling" (of low aspect/profile tires) "a lot safer" How so? Most folks I know prefer the combination of larger diameter rims with low profile tires for the looks. For a laid-back driver like me, it means having to pay more attention to where I am within my lane on the highway, or where the car is pointed in general. The much wider, lower profile combination of wheel and tire on cars since 2010 has made driving, for me, a more two-handed steering wheel experience, compared to before, with a narrower rim and higher profile tire. Those tend to want to go straight, and are less subject to tramlining and being tugged side to side by a variety of road imperfections, such as joints, pot holes, or small stones littering the drive lane. Additionally, on a car with lower profile setup, higher degrees of self-correcting suspension alignment angles, such as Caster, and SAI(steering axis inclination) or 'kingpin angle' as we called it long ago. I don't really feel any benefit from the sharply more responsive steering afforded by huge wide wheels with super low sidewall strips of rubber wrapped around them. I could see the advantage of such a setup, however, in a competition theater, such as a car race
How beautiful! I feel like I am in the classroom as I watch this! I miss those days!
Professor. Krishnakumar lectures are world class.

very nice presentation ... thanks for sharing
Wow Excellent Teaching
Long time we didn't see new video of tyre construction pls make new
Can any one say what other materials can be taken instead of Elastomers for the same application?
Amazing simply amazing
28 k views...!! Engineers have time to watch so many other videos but not like this one..
Very good explaination sir
I did not understand how the frequency is effecting the glass transition temperature? can anyone please help me.
Sirs ur not wearing any Identity Card in videos
Sir please describe the tire latring
can someone please explain what does this "modulus" exactly mean ? 37:15
Modulus is the ratio of stress to strain of a material under load.
Sir how to calculate tyre stiffness
it's very nice sir
Thank you Sir
sir which book we can refffer for vechicle Dynamics
Wong and Gillespie
Why temperature decreases when frequency increases ?
I have same doubt...I think he was saying glass transition temperature decreases with increase in frequency
So good
Drank 5 cups of Coffee watching this.
it's understandable on it
Now I know why most of the people's saying that our education system is wrong.
Ashwin Revankar what makes you say that?
Sir, atleast show the tire well... I didn't understand the orientation of tyre. This is why we need 3D visualization.

this shit's blessed
Very poor presentation.
Hi sir, I appreciate your comment. But I need a good presentation to compare. Can you please provide that?
