I hope this is not a dumb question, but what type of wood should I use when replacing the Treads on the outside front stairs? The previous owners used Pressure Treated boards. For one thing, they are quite ugly since they were not stained or painted. Yet I don't think that that is really the solution. I look at other homes around the area, and the treads don't seem to be made of PT wood, but maybe Cherry/Oak/Maple? My local Home Depot doesn't seem to carry treads for outdoor stairs.
