Maintaining proper inflation pressure contributes to fuel efficiency and longer tire life.

Executive Summary

Using concentrated nitrogen instead of atmospheric air to fill tires can slow down the loss of natural tire pressure in truck tires. Having appropriate pressure reduces tire wear, inreases fuel efficiency, and leads to fewer roadside breakdowns due to tire failures.

To fill tires with nitrogen, a membrane process is used to remove oxygen and moisture from the air, which takes advantage of faster permeation rates of these components relative to nitrogen. The highly-concentrated nitrogen gas is collected in a pressurized storage tank, which is then used to inflate tires.
