Wheel Width

^do explain

if you are thinking about ride height/height of tire, that's a different thing...

I think stretching the crap out of a skinny tire on a wide wheel is what he's talking about. You'd have an angled sidewall, so the tire must be closer do the wheel (making for a smaller diameter).

But he answer is still basically no

that will change the height of the tire, not the circumference...

Changing the height of the tire = changing the circumference... a shorter circle has a smaller circumference.

This. The same amount of rubber will be there, but it'll be stretched/contorted a little differently. It would be measurably but insignificantly different.

I was really just being a smart-ass though

I guess it depends which circumference you are wanting to measure. Exterior (tread), lip, or interior. I would contend the lip measurement would change little enough on a stretched tire to be inconsequential, however on the same tire when the sidewall angle changes the exterior diameter of the tire should shrink, albeit probably very minimally.

i wanna see how you magically change the circumference of some rubber that has been formed to a shape without cutting/modifying it...
