you transfer the power to the ground via the tires, that power/energy will deform the rubber (make the raised parts of the tread flex), the more flex the more resistance, when you spread out the contact patch you reduce the flex on a given area. the downside is that when you use wider tires you COULD increase your frontal area, depending on the ride height of your car and how much tire is exposed
