Yes, but I don't see how that's significant, outside of marketers trying to make the effects of increased tire width sound more significant than they are by expressing things in terms of some value that happens to grow quadratically.
Doubling the width gives you four times the volume, but for the most part, most of what appear to be the relevant consequences change by a factor of two. The amount of tire distortion for a given linear deflection is halved. The amount of travel you have before the tire bottoms out is halved. Once PSI is adjusted per width, the amount of air that goes into the tire is only roughly doubled. And so on.
What consequences quadruple as a result of the volume's quadrupling?
