How to Size Motorcycle Tires

How to Size Motorcycle Tires

See those numbers on the sides of your tires? They tell the complete story of that rubber, including its dimensions, abilities, date of manufacture, and more. But decoding tires can be a frustrating experience. Lemmy's not too fond of the current system, but he understands it, so get up to speed on reading tires. Next time you're due for replacements, you'll decipher your sidewall in no time.

When it comes to tires, since I only have two tires I always put on factory recommended tires. Good information and I learned something. Nice job!

Welcome to tire sizing, where the units are made up and the practicality doesn't matter! I used to work in a tire shop, so I feel your pain on trying to explain this to people. Too often you get that blank stare, sometimes you even see some electrical smoke coming out of the ears!

Dang Lemmy, you loosing weight. Awesome 👍

[Roy_Godiksen]

Seriously, who decided to use every measurement unit in the world at once to measure motorcycle tires? That's just dumb.

It surprised me at the dealer and a major motorcycle gear chain I was told the B and ZR were speed rating not radial and bias belted indicators thanks for clearing that up

[drjones]

Wow I'm still confused but getting so much closer to understanding going to honestly watch this again 4 or 5 times until in syncs in but great video thanks you keep the great content coming

What a short simple way to explain! Great 👍🏻

But what about weight load on tire? In instruction is 76h but most tires has 73h. How about that? Im wandering...

[habanadj]

At the beginning of this video I was saying to me: I do know what those numbers means, the truth I don't know nothing about tires numbers

[CoachSteveu]

Thank you Lemmy! Very helpful. Wacky but I understand now.

Hello .. is it ok to change tire height of the tire like from 55 to 60 for S1000RR 2020 with no problem going to track day ?

[wmrider_adventures]

Hi! I've seen many people discussing going up a size, but I can't seem to find info on going down. I'm struggling to find a good rear tyre for my Yamaha SR125, and I'm wondering if instead of 100/90-16 it would be ok use 100/80-16?

[smaad]

Thx ☺️ A LOT I was close to a huge Mistake
I’m ordering new tires on Amazon and thought 120/70 12 is the same as 130/70 12 but according to you no
Since my scooter is a Vespa and the rear tire is at 1mm from the suspension and the exhaust imagine if I’ve chosen the 130
Thx 🙏🏾

Cheg Chin C755 HT 3.25/3.50 x 21 i use on my 2 x Yamaha YZ465H's, Honda XR630, KTM 690, 950 & 1290 but no longer made im down to my last tire i had, desperately trying to find a equivalent tire
There long wearing excellent in hard ground & deep sand with the wide print, there almost double the width to a Motoz tractionator desert 90/100 x 21

Thats why I love mud tires, it's all in inches well for the most part. 37"x13.50" R18 is what I'm running and im pretty sure all of you can understand that

[jbell]

Can I use a 110 90 18 if my bike manual says 110 80 18?? Will the speedo just be slightly affected?

[samueljjackson]

Hey Lenny, Great videos I have been watching and a lot of education. I have Honda cb350 highness with front tyres 100/90r19 & 130/70r18. Do you think by changing the rear tyre to 140/70r18 or 150/70r18 would have any sort of negative affects on the motorcycle.

[FaizanShaikh-rjfs]

If i chand bike tyre ASPECT RATIO than what's the affect on bike MILAGE, CHAIN SPROCKET and SPEEDOMETER.
