Economy Tire offers you a choice. You can use nitrogen, not ambient air, to fill tires with the new Nitrogen Tire Inflation System. A revolutionary technology in tire inflation. You gain a competitive edge by enhanced tire pressure retention. Bringing tire inflation and, in turn, travel to a new level. Nitrogen improves tire performance, road safety and cost savings!
Better air pressure retention. The single biggest reason for tire failure is lack of maintenance of tire pressure. In fact, 54 percent of all vehicles on the road have low tire pressure. Oxygen in compressed air can permeate the tire wall reducing tire pressure. With nitrogen, diffusion is 30 to 40 percent slower than oxygen. As a result, nitrogen maintains tire pressure longer than ambient air.
Enhanced fuel economy. Maintaining tire pressure can boost fuel economy by as much as 6 percent. Nitrogen disperses heat more quickly than ambient air. By restraining the heat in the tire and reducing rolling resistance, you get better fuel economy.
Longer tread life. With quicker heat dispersion, you get a cooler running tire which helps extend tread life and reduce tire failure. Nitrogen also prevents oxidation which can not only lead to tread separation and belt failure but, when combined with moisture, corrode rims. In fact, moisture can result in rust flakes that can fall into the valve stem, block the valve and cause under-pressurization. It can even cause the valve stem itself to rust.
