At TireTrends™ we offer free Nitrogen inflation on any purchase of a Tire & Wheel Package. You have invested a significant amount of money and we want you to experience optimum performance and service life.

Why should you choose Nitrogen over regular air inflation?

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.

Slows chemical aging. Filling a tire with nitrogen also significantly slows the chemical aging process of the tire's rubber components. This leads to fewer catastrophic failures like blowouts. Slower aging lengthens tire core life, which yields extra retreads and lower fleet costs.

What is a Nitrogen Generator? Nitrogen Generators employ advanced membrane technology for flawless performance, day in and day out. Nitrogen Generators are comprised of a bundle of hollow-fiber membranes that separate nitrogen from the air. When the compressed air passes through the fibers, oxygen and other trace gases permeate the membrane, due to their smaller molecular size and higher molecular bond strength. Nitrogen, which doesn't permeate the membrane, flows through the outlet port to the application.
