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

I'm thinking Hallmark invented the "N2 in Tires" idea. They tend to make men spend money on women for various unneeded holidays, and have therefore created a money making source of income......much like the guys that think that adding only 22% more N2 to tires will give you that gooooood feeling that your car is different and better.



Let's not lie; we all thought it was a cool idea until we remembered in our Chemistry classes that air is 80% N.

Then it became another gimmick like 5 hour energy. My roommate in college swore that drinking two in a row would give him 10 hours of energy.
