Understanding motorcycle tyres | Home Schooling Lesson 12

What do the grooves on a #motorcycle #tyre do? Why do they have three compounds? Do they need to rotate in a certain direction? What pressure do I need? All of these questions and more are answered in the latest #lesson in our Home Schooling series, in conjunction with Honda Engine Room.

We're aiming to educate and entertain with a series featuring simple explanations of motorcycle components and how aerodynamics or weight affect the bike as well as details of how an engine or ABS works. See the playlist for all episodes.

Out riding earlier today and was wondering about the physics on cornering with regards to the tyre. Was looking for a physicist’s opinion on it all but here we are. Fantastic stuff. Really informative.

Depth of the tyre is a % of the width...

So, R17- 200-50 means; 17 inch tyre - 200mm width and 100mm (50% of 200mm) depth.

[riccardocarbo]

BB... it is not correct to say (when given the size 190/55) that the 55 is the depth of the tire--not so. That number is called the aspect-ratio. The 55 means, that 55% of the 190 is the depth of the tire. So, 190mm across, but 55% of that, is the depth=104.5mm. You could say there's more clarity in a number showing how close to the ground the rim rolls over it, but that would ignore how wide it is, and wider ones give better cornering than a narrower tire of the same depth. However, by using a singular number (aspect ratio) you can account for both depth and width in one measure. This gives a clearer picture about performance rather than simply "depth."

Good as always Adam. Well explained and delivered. Cheers

Ur videos had been a great help in understanding bikes furthermore. Great job and thanks

[chrishall]

I thought the depth measurement was a percentage of the width? Not mm?

[tinygoesaround]

I learn a lot from you, thank you sir

[OregunAdventure]

Great video. I have a 19' CBX and had a bad experience with the Shinko 705's. Gonna try out the Dunlop Trailmax Mission tires.

[robholloway]

Its a minefield tyres but usually go with Bridgestone as I feel confident with them, well explained as always Adam 😇

[justaguyreal]

5:00 and the bike manufacturers are fully aware of these improvements in tires as well as everything else you state, so why they still recommend 36/42??
But you do have some good points.

[tritontwo]

Cheers, well presented & delivered.

Really useful and interesting video. Would you know of any companies that can change my tiger 800xca wheels from tubed to tubeless 😒

[monicamurray]

I ride a cb650 bought new in July 2017 fitted with Dunlop Sportsmax D222 tyres. I have read lots of reviews of these tyres and have yet to read a good one, and after a couple of twitches i am looking to buy something different. After seeing this vid I checked my tyre numbers and was amazed to see made in Thailand in 2012, so the tyres were 5 years old before they even hit the road. Having read elsewhere that tyre manufacturers recomend changing tyres after 5 years regardless does anyone else think I could have a claim against Honda for fitting 5 year old dodgy tyres on a brand new bike.

GODBLESS YOU ALL🙏
BEAUTIFUL SOULS💕

[emmanuelgeorge]

Hi i have a lexmoto lxr but am not a fan of the cst tyres that comes with it am looking for a all weather tyres any help

[mohammadsyafiqwilson]

Zx10r year 2009 . What is the best size?

[familymemories]

Excellent video I just have one question if my bike running a view rated speed and they have upgraded to a W rating will this affect the handling thank

[aashirwadtripathy]

How to choose tyre pressure if I change my tyres to an aftermarket one from the stock ones. Should I run em with the stock tyre pressure?

[saheelmaulingkar]

What should we do when the tyre wears partially, what should be the tyre pressure? As per recommended or lower it as per feel?

[Kickassdave]

I was hoping for a little extra info in terms of types of riding vs different types of tyres etc.
I'm not a mega fast rider, but my bike is a fast bike (a Ducati 959) and I only ride on normal roads. So I'm always struggling to decide exactly what type of tyre I should really be running with. I am occasionally in the rain, but not so much anymore, so I went with Michelin Power RS tyres... but should I have just went with more durable or multiweather orientated tyres??
