A lot of tire centers are offering this service. Anyone done it? Worth it? What did it do for you?
Let me guess, you're a Nitrogen salesman? :lol:Why use Nitrogen?
Less inflation pressure loss
Reduced wheel corrosion
Prevents inner-liner rubber deterioration by oxidation
Tires run cooler
Increases tread life
Increases fuel mileage
Helps prevent uneven wear
Oxygen in compressed air permeates through the wall of the tire, thus reducing the tire's inflation pressure. During it's journey through the tire wall, oxygen oxidizes the rubber compounds in the tire, causing under-inflation and deterioration of the rubber . Dry nitrogen will maintain proper inflation pressure and will prevent auto-ignition, will not corrode rims, extends valve core life, and will help the tire to run cooler. Experts in the tire industry indicate that oxidative aging is one of the primary causes of decreased tire life. Oxidative aging is caused by the diffusion of oxygen from the pressurized air cavity of the tire to the outside atmosphere. Tests have shown that if tires are inflated with nitrogen, there is a significant reduction in tire failure. While both nitrogen and oxygen can permeate rubber, nitrogen does it much more slowly. It might take 6 months to lose 2 psi with nitrogen, compared to just a month with air. And nitrogen is far less reactive. It doesn't cause rust or corrosion on steel or aluminum, and it doesn't degrade rubber. Wheel surfaces stay smooth and clean, rubber remains supple and resilient.
Just wondering - if it's so unstable, then why do you run it normally offroading and beach driving?I now use C02 for offroading/beach driving, and wow is that stuff unstable. When it got cold out I was about 15 psi lower than my normal with that stuff in. So, C02 is good to use in a pinch, but just check your psi alot when you are running it.
Question. Does the tire shop evacuate the air out of the tire after it is mounted, then put nitrogen in? If not, the tire is already filled to 14.7 psi absolute pressure before you add the nitrogen. I would like to see them evacuate the air, because doing so would pull the tire off the bead. So, you still have air in the tire, not 100% nitrogen. If you fill the tire to 60 psi, you have a 20% air 80% nitrogen mix. The way I look at it, air is 78% nitrogen anyway, so you aren't gaining that much. Regarding air loss, I never have to add air to my tires unless they get a hole in them.
