Cheap Tyres..

They are good if you're riding boards and worry about rim touch on the banks. On a totally smooth surface the narrower tire might have an edge on a wider one, but any 'normal' road surface will increase hysteresis and result in higher energy losses compared to the wider tire - up to the point where the sliding friction of the wider contact patch outweighs the internal hysteresis value.
