Any articles I've read about nitrogen in tires seems to indicate that the benefits are so slight that the money you spend for a refill would be better spent in a good tire gauge. Followed, of course, by checking the tire pressure regularly. There is also the inconvenience finding a place that sells nitrogen or, if refilling at Costco for free, finding a time and place to pull your rig into their tire facility which may be busy, crowded or both.
