"nobblies" will increase rolling resistance as well as aerodynamic resistance .. so the engine has to work harder to get the same speeds .. so you could well use MORE fuel not less .. :)

cheers entwood i thought the drag factor would make a difference but with them being bigger thought that would counteract
