Toyo Open Country AT2 - MPG vs Stock for '1/2 ton' owners

Sometimes when I am standing at the highway, waiting to cross the road, a four by four will go by, large lug tires on all four wheels, and it's loud; much louder than a mud and snow combination.

Noise takes power to produce. That's why they make cars more and more streamlined. Sleeker and quieter gives better mileage.

Having said that, if you like your Toyo's and take them into places where the lug tread will be more fun, who cares about the mileage.
