We use it on tires, struts, hydraulic ressvoirs and accumulators. We use bottles but I know that when I was in the military we had a few nitrogen generators. Very expensive back then. As they are becoming more common the cost may become more business friendly but even with our volume we can't justify anything but bottles. Mind you our bottles are in a cart with a regulator/booster that is worth 5g's or so. If nitrogen is that much better for tires I would imagine trucking fleets would benefit from it's use. How long does a tire last before it gets chucked these days. I've never heard of a problem with inside tire wear (how many times can you recap a tire) so I would suspect the big gain is stable tire pressures which give better, more consistent gas mileage. On the stock car after just 25 laps our tires pressures can rise 15-20% using air.
