I just bought a 5th wheel. I have yet to take possession of it:), I notice the tires are serviced with Nitrogen. So how do I maintain nitrogen filled tires?
I bought new tires for the truck, they filled them with their nitrogen,(free) I do notice that the pressure does not fluctuate with temperature like the 78% does. Does it make a practical difference? Not that I can tell. Would I pay for it? Hell No!
