Rolling resistance is cause by deflection in the casing and sidewall of the tire, and a wider tire will have less deflection. Just make sure you have some good fast rolling tires. (Sadly, in general, the best hand-made low-rolling resistance high TPI count tires are only made in narrow versions because it is what racers usually use due to lighter weight)
