In my experience with a Time ADH01, I am running 28 Pirelli tires and could go to 30s if I wanted. The wheels are Campy Shamal Ultra with a 17mm inside rim width. I feel that wheels are really the determining factor. If I were using some wheels with 21 or more inside rim width, 30s would be a poor decision.
