   rob, there are several variables I would consider for an answer. Assuming the floor is to be milled t & g, I would consider the species of pine, the growth factor and how it was milled. Southern yellow pine, especially some of the old-growth recycled boards, I think you may safely be able to go to 7" or maybe even 8". White pine or younger growth milling, I would set my limit to 6". Some of this is due to seasonal movement. SYpine with it's high resin content is more stable than say white pine. You have less shrinkage and less potential for cupping. This is also the consideration behind the milling. If you have boards plank sawn which may be more likely with wider boards, you increase your chance of cupping across the heart grain.

   If you wanted the widest boards possible to be nailed on edge, I would look for some recycled old-growth wood for my flooring.
