Custom tires technique question

[Cat966c]

Hey what's up? I was just thinking about a new technique to make home made tires; what if you took an equal diameter tire, heated it up till it's malleable-not liquified-and re pressed it into a new mold with the desired tread pattern. Would that work, or would heating the tire up de-sulfurize it? I was thinking the rubber would remain the same because it's not liquified, and that is what the heavy equipment tire companies do.
Let me know your opinions, thanks
