Get Nitrogen Institute

Driving on underinflated tires? If you are, it’s like driving your car through sand!
The engine has to work harder, burning more fuel and adding wear to engine components.
It’s also dangerous. Almost all tire blowouts are caused by underinflated tires. Tires lose 1-2 PSI every month!. That’s 6 PSI low by the time you have your oil changed!


One Solution: Check your tire pressure every month


A Better Solution: Use nitrogen (N2) to increase your tire pressure retention, fuel economy, tire life and safety.



But don't just take our word for it. Look at these test results performed by a variety of groups, from private studies to research labs. They all agree that nitrogen tire inflation reaps benefits.

1 - Dunlop Tires, Rubber Association of Canada
2 - price of $3.00/gallon,
3 - average tire life of 45,000 miles for passenger and 230,000 miles for fleet,
4 - average tire cost of $100 for passenger and $275 for fleet,
5 - the 23% fuel savings is derived from decrease in rolling resistance, not road tested.
