Nitrogen Filled Tires
My trailer came with nitrogen-filled tires. I'm not sure it makes that big of a difference, considering the atmosphere is already 78% nitrogen. I find conflicting literature on it as well. Anyhow...

Hi,
Any 'problem' with using compressed air to fill your tires is that it might contain some moisture. It will not directly damage the tires, however when a cubic centermeter (10cc) of water is heated to 212 F and turns to steam, it will expand to 1.6 liter of steam! So it expands 1600:1.
So those few drops of moisture in a not so well maintained air compressor can make a difference on the tire pressure when running on a hot day, or using the brakes down a hill.
Normal well maintained compressors, with a filter / dryer on the outlet to control moisture, you will be fine. Normally they empty the air compressors of water every week or so.
So fill it with normal compressed air, that is what I do.

I use a TPMS to monitor my tire pressure and temperature. I live in Tucson, and pull my FW on some extraordinarily hot days. Even when the ambient air temp is 110 degrees F, the temperature of my tires rarely exceeds 120 degrees! I don't know of any tire that wouldn't fail between 160-180 degrees. Hitting the steam point of 212 would be impossible in my opinion.
