Not sure how this went from tractor tire ballast to nitrogen in road vehicle tires, but since some in here seem to be proponents of the “pure” (maybe it is) nitrogen dealers are pushing, one of the issues I have with nitrogen only is I rather routinely drive a 4WD. Contrary to what seems to be common wisdom that most 4WD vehicles never actually leave pavement, mine leaves pavement quite routinely. That same truck also gets used for towing a camper and equipment trailers routinely so it runs 10 ply rated mud tires rated for both stability towing and puncture resistance off road. They’re rated for 65 psi but of course that’s the tire rating, not vehicle mfg suggested.
When driving on loose sand or really sloppy mud, reducing tire pressure to around 12 psi is SOP. 12 psi ain’t working for high speed pavement duties. Trailering above about 5K gross on the trailer: 45 psi in rears, 35 psi in front gives good stability. If I’m just riding around on pavement sans trailer, 32 psi in all 4 rides better.
I have a tire inflator in the truck at all times to allow for all this. It doesn’t take up much room behind the driver seat. Never had a problem with any of this. Not really sure how that would work with nitrogen as I don’t really care to cut my already limited cargo capacity (it’s just a pickup) by constantly toting around a nitrogen bottle.
