Short answer: it depends.

You can find a good discussion of aero losses vs tire width in this thread: http://ecomodder.com/forum/showthrea...g-cd-7475.html

You can also use the aero/rolling resistance calculator to estimate effects of changes to Cd/A & RRC from tire changes: http://ecomodder.com/forum/tool-aero...resistance.php
