Confused about tire aspect

Okay, googled and found info on tire size designations. says that for a tire that is 130/90-16, "90" is the aspect ratio of the tire width * height / 100. So practically, if the 130/90 were an 130/70, would that mean the tire is not as tall?

I'm looking to replace my 110/100-18 rear with either a 100/90-18 or a 120/80-18. Is the 120 wider but not as tall as the 100? Which one would generally be better? Thanks, you guys rock. :thumbsup:

A 110/100 is close to a 130/90. The 100/100 = 120/80 and the 140/80 = 120/100 on dirt tires.
