Hey white gardens: do you have a problem with your front tires falling into the wheel tracks of the rear wheels? I noticed this on my old bosses F550.
From what I have picked up about DRW over SRW. You'd go through less tire wear, as loads pulled sit more spread out over the four tires instead of two. In snow you'll get more points of contact to a surface so less spining tire, that can lead to drive line failure. But need a wider plow to cover your track.
This my pratice, probably not the best, but I change out tires in the front (steering) seperately from the rear tires. Helps with cost a little, not a bigger up front bill.
