Nitrogen will have no different effect on tire temperature as long as you fill the tire to recommended pressure with it or compressed air. There is no magic cooling effect of that gas which is already 2/3 of the regular atmosphere anyhow. The only advantage to it is that it is supplied as a dry gas if you do not have access to dry compressed air. In my rig I do have a drier so I get that from it to fill my tires.

Even if you fill up with "wet" compressed air the inside of your tires will still be in far far better shape than the outside sidewalls that are exposed to sunlight and ozone.
