Some time back, I read about how filling your current tires with Nitrogen as opposed to regular Air will help to keep a constant Air Pressure, Reduce Oxidation and in the end give you better Gas Mileage and a Longer Life for your tires.
I thought that sounded like a great idea so I went on a search to find a Service Station in the area that offered Nitrogen. I must have called 30 places before I found a few websites that will let you search for a station in your area.
I ended up going to Spring Chrysler Jeep Dodge. It was right around the corner and they charged $49.97 to fill up all four. From now on, they will top off my tires for FREE whenever it is needed.
I was also surprised to see that I got a little over 400 Miles on my next tank of gas! Wow.
I thought I would post the links that helped me for anyone else who may be interested. These two links are for the actual Manufacturer of the equipment that the service station or Dealership uses. Look for the link that says Find a Provider.
