re: Nitrogen filled tires- Does it help with pressure loss in changing temperatures

I have had nitrogen on my last two trucks from the factory or dealer, it still fluctuated. I work in the plant and had access to 99.99% nitrogen and put that in my tires, wasn't nearly as bad but still fluctuated.

Most places have nitrogen/air separator compressors that will get you in the 95% range some may be higher, but as you go higher the cost of the machine compressor goes up ans. I would never pay for nitrogen.
