File this under “Every Little Bit Helps.”  Just saw a news story on this car tire product that may increase you gas mileage by inflating your tires with nitrogen instead of air.  The manufacturer claims nitrogen filled tires can maintain proper pressure up to 60% longer than air which will lead to a smoother safer ride, better gas mileage and extended life on those tires keeping them out of the landfill.  The UtraFill 99+ pumps are located at dealers and gas stations nationwide.

The manufacturer, GoNitroTire,  also makes TireXtender, an aerosol can-based product available in most auto supply stores for topping off your tires with nitrogen if you notice you’re sporting soggy wheels.
