whazz the advantage .................and where does one get nitrogen to fill tires with?
ROPD said:I was skeptical about the nitrogen thing too but when you buy tires at Costco they fill them with the stuff automatically.? And you can stop by any Costco where your tires were installed and they will top them off with nitrogen for free.? Plus I have yet to find anyone who can beat tire prices at Costco.? Unfortunately they no longer have a contract with Bridgestone.
But back to the topic at hand.? From what I read the main advantage to nitrogen over straight air is that the nitrogen molecules are larger.? And since all tires breathe (leak) some through the sidewalls, nitrogen filled tires retain proper air pressure for several months at a time as opposed to straight air fills which should be topped off much more frequently. Hence, for the driver who doesn't maintain proper air pressure on a regular basis, pressure remains higher and theoretically this will provide better fuel economy.
Now, I ain't no scientist but this kind of makes sense (from the common folk's view).? If I'm wrong somebody set me straight.? In the meantime I'll keep going by Costco every 2 or 3 months and have my nitrogen checked.? At least until my Bridgestones wear out and I have to buy tires elsewhere.
