it stands for the width in inches mainly the tire width the tread width is usually different, look at www.intercotire.com and look at the tire size and specs

No, when dealing with say a 31/10.5/16, the 10.5 stands for ~10.5 inches wide. a 31/12.5/16 would be ~12.5 inches wide. Both would be the same height.
It's only when dealing with metric sizes that it's a ratio. 235/70/15 means that the sidewall height is 70% of 235 (width) and it fits a 15" rim.
