>Tires lose pressure over time and that means worse gas mileage. During the the presidential campaign last Spring when gas shot up to over $4.00/gallon, Barack Obama suggested a simple and quick way to help save on gas – check your tire pressure. Regrettably, most Americans don’t bother to do this.
One of the first things I came across was inflating your tires with nitrogen. Nitrogen molecules are larger than oxygen molecules and leak out much slower. According to the Get Nitrogen Institute, tires filled with pure nitrogen tend to hold proper tire pressure longer than tires filled with regular air. With nitrogen tire inflation, there are improvements in handling, fuel efficiency and increased tire life.
