As said above, keep them unless you have a problem. It sounds like for what you are going to use them for, they are unnecessary, but unless they are tough to balance, run them as is.
Standard rims you can drop tire pressure safely to twice the width of the rim. For example, an 8 inch wide rim, could safely be reduced to 16psi for off-road travel. Obviously, an hour down the freeway, at 70 miles an hour, is not going to be great for your tires, but also, you can reduce psi further to get unstuck, if you are careful not to roll a bead.
With bead locks, you can effectively run the tire at or near 0 psi.
