I have been told by our local tire dealer that since nitrogen is an inert gas you not will have the fluctuation in psi when tires warm up. How true is this statement? Thanks for your input. Skip
If you change the nitrogen in your tires every 2 years, you won't have to replace your tires at 7 years.....but you have to rotate them also in order for this to work....and you have to carry a spare on the roof (no rim). It's all here in the threads.
