You do not see the temperature swings we do. 90 degrees to -32 f here. That certainly causes loss of air.

Given that even N2 follows the "Gas Law" i.e. PV=NRT I would expect you to see about 2% change in tire pressure for a 10°F change in temperature.

I know Canada can get cold but didn't think you saw 100°F change in temperature in a day

When we lived in Moline-Bolingbrook, IL, we had temperature swings from -28F to +98F, but it sure wasn't in one day. Besides, we didn't camp when it stayed below freezing for long. Usually stopped camping in Nov and started again in Apr.

Unless the tire mounting is done in a sealed chamber, and the guy mounting the tire is wearing an oxygen mask, the initial fill of the tire is with ordinary air (a little less air at 6,000ft in Colorado Springs) at room pressure. So you are never getting 100% N2 in your tires unless you vacuum out the air and replace with N2.

So, no, I don't do nitrogen despite the tire store's effort to sell me. And since I check my pressures regularly, and add/subtract air as needed, the reduced loss of pressure with time is unimportant to me.

And I already have the benefit of low natural humidity.

My 2016 came with Nitrogen. One side is roughly 10 lbs lower than the other side. Can I top off with just normal air? The drivers side sits a little above 70 psi the passenger side is right at 80 psi. I must admit that when I picked up from dealer last year I did not check the psi so no idea if they leaked or were not filled properly to begin with.
My storage place does not have electrical hook ups so it's a pain to do work on mine. I think there is a truck stop close by that I could use to top off the tire.

I have topped mine with air, I do believe dry air is the best if available. So to answer your question yes top them off the little bit of air will make no difference IMHO

I'm a refrigeration tech and we use nitrogen by the cylinders. I use it on my tires all the time. I wouldn't pay for it if I had to but it does maintain a more consistent pressure than air does.

I just heard that if you use helium it will make your rig float on air.
Here is a picture that proves it.
I read it on the internet so it must be true.

Posts: 45 per Michelin but would apply to any reputable tire manufactured today ...Nitrogen is an inert gas. It is simply dry air with the oxygen removed (air contains nearly 79% Nitrogen). The physical properties of nitrogen reduce the pressure loss due to the natural permeability of the materials of the tire. Unfortunately, there are other possible sources of leaks (tire/rim interface, valve, valve/rim interface and the wheel) which prevent the guarantee of pressure maintenance for individuals using air or nitrogen inflation. Tires manufactured by Michelin are designed to deliver their expected performance when inflated with air or nitrogen, as long as, the user respects the pressures recommended by the vehicle manufacturer on the vehicle's placard or by the tire manufacturer. Whether they are inflated with air or nitrogen, regular pressure maintenance remains critical because under-inflated tires lead to:

- a reduction in road handling
- a reduction in wet traction capability
- an increased sensitivity to road hazards
- a reduction in treadlife
- an increase in fuel consumption
- a reduction in tire life due to excessive heat from over deflection
