Re: Nitrogen vs Air in your tires
I use air. Always have.
My issue with pure nitrogen is that air is 78% nitrogen, I don't think there is enough difference between them to make a difference. Most people will replace the tires before oxidation inside causes an issue. Remember the treads are still exposed to the elements. What makes sense in racing doesn't always make sense on the street.
As far as mileage difference after changing tires, I experienced that issue when I replaced the tires on my Colorado. The new tires are a different formulation of the rubber compounds (different manufacturer) and I lost 2 MPG afterwards. What I lost in mileage from the General tires that GM put on the truck, I more than make up for in handling and wet weather capabilities with the Firestone tires that I replaced them with.
