Tire size?

[JE223]

OK, I am a little new to this game, but shouldn't tire size be pretty simple? I have destroyed my first Bridgestone, so I decided to get a new tire for my KX-250. I like the tread on the Michelin, so I bought one. I bought a 120/90-19. I had a 110/90-19. I thought this would be a wider tire. It's not. It is thinner. The salesman assured me it would be wider. What's up? Should I run this tire? I can keep it for the 125, so it would not be a total waste, but I am still confused.

Take a look at this thread:

It and many others like it can be found by doing a search on "tire size" or "Michelin tire size" :)

that tire IS wider. it may not look it, but it is 5 mm wider on each side of the tire.

120/90X18 = 100/100X18 = 4.00X18
130/80X18 = 110/100X18 = 4.50X18

The Michelin that he bought has tread that is norrower than the Bridgestone that he was replacing.
