I'd like an engineer to explain how high capacity singles can yield improved mileage over duals. ASSUMING that both tire setups wind up with the same overall size rubber footprint on the road surface - how can better mileage result?
I can understand about traction in the snow: The two slender tires in a dual set will sink deeper into the soft surface to reach solid ground than a single wide tire will sink. Everyone familiar with truck traction knows that fat tires provide more flotation ... but you don't want more flotation where there is a slippery snow surface that you don't want to float on ... you want to sink down through the snow to reach a solid surface to get some bite into.
