Better air pressure retention. 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.
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.
Slow chemical aging. Filling a tire
with nitrogen also significantly slows the
chemical aging process of the tire’s rubber
components.
