By using dry nitrogen gas instead of compressed air to inflate tires, a department will maintain proper inflation pressure and prevent one of the major causes of tire failures. That's why many of the major tire manufacturers are now recommending the use of nitrogen for tire inflation. Dry nitrogen gas will extend tire life by up to 25 percent and will improve fuel efficiency by up to 4 percent. In addition, it provides more consistent tire pressure and reduces or eliminates the need to check tire pressures and top off tires.
