Does tire width include width of knobs?

Hi all,

I'm looking to get some fatties for the SS I just built and was wondering:

Does rated size (eg 2.3", 2.5") mean the width of the body of the tire, or the width of the very fattest part of the tire? I ask because some of the tires I'm looking at have knobs that appear to stick out past the sidewall.

Thanks for the answers to the noobish question!

Usually the width is from the fattest part of the tire (knob to knob). Which is misleading.

You will find the numbers misleading. A 2.35 tire will be all over the place as far as widths go depending on the brand.

Great question. So does that mean that a 2" fat slick is generally wider than a 2" knobbly?

2" slick will probably be more narrow than a 2 inch knobby ... that's just my observations though..
