•Normal driving heats up
and expands the air in your tires.Parking on cold surfaces cools and contracts it.
Fluctuating tire pressure can set off your Tire Pressure Monitor
System, falsely indicating your tires are under-inflated.
•Because Nitrogen
doesn’t expand and contract like Oxygen does, replacing the air
in your tires with Nitrogen helps to minimize this headache.
Oxygen steadily leaks from tires. But larger Nitrogen molecules stay
in tires much longer.
