Tire Sizes

[90GTVert]

This is just a little list I put together of some tire sizes to make finding what might fit your application a little easier. Some info is missing for certain tires. If you know the missing numbers, shoot me a PM.

Please note that these are not exact numbers. For example, one manufacturer's 100/90/10 may be taller or wider or shorter or more narrow than the same size from another manufacturer. This is just a basic guide to get you pointed in the right direction.

Hi fellas and ladies!
  I recently put a different rear rim and tire on my scoot due to a gear change and I really started to notice the difference in sizes/circumference of tires. For example, here's two tires of the same size (120-70-12) side by side- both on 12" rims. As you can see, there's a difference in circumference here. I was thinking maybe the rims were different widths, but that's not the case either; they're both 3.5". Basically, the rim on the right has a much taller "bead area"- I really don't know what else to call it- that keeps the tire "taller" It has a sharper "egg shape" to the profile of the tire, where as the Adly rim on the left has a much shallower "bead area" and lets the tire go wide which makes it shorter....



Wanna see a really big tire on the same sized rim?? Here ya go!:



Lol, if you're looking for additional top speed on top of that upgear- this might be the ticket! (Btw these tall tires are on a Mina longcase- Baccio)





   Unfortunately, the tires don't have the size on them- they just say "4.00-12" even though they are on a typical 3.5" rim...
Here they are next to the rims/tires on my scoot now:




Just wanted to show Y'all the crazy difference tire size can make!
