Load Range D tire confusion

So comments from Mark Twain and guidry got me doing a little more research. From Discount Tire, it turns out I can get the load range E GY Endurance ST225/75r15 on 15" Liquid Metal Supreme HD steel wheels (rated for 2835 lbs!) for a couple hundred more than my initial plan. I'm thinking this is the way I will go. I can try to sell off my 14" wheels (two alloys and a steel) and their mounted tires, which are in decent shape, to recoup some of the cost. The up-sizing will add basically 1" in radius, which I don't see as being a problem. Any reason not to go this route?

Thanks for the comments.
