Now, on the other hand, if what you are really asking is: "Is there a difference in the tread wear of my truck because it is a 4 door as opposed to a two door because of possible differences in weight distribution? The answer is no. The added cab space weighs the same amount (within 100 lbs. or so which is shared by 4 tires) as the portion of the bed that it displaces. Once the truck becomes heavier because of increased mass, like a 4Runner or a 5Runner or a 2Runner with bricks in the bed, the tires wear about the same as those on a lighter vehicle because the increased weight on a heavier vehicle is offset by the wear created by "wheel spin" or decrease in traction of a lighter vehicle. At that point the difference becomes one of gas mileage. Wanna know which one gets better mileage? It depends.
