Nitrogen Filled Tires

  

Using high purity nitrogen to inflate tires is nothing new. Nitrogen has been used for years to help increase safety and tire performance in airplane tires, military vehicles, race cars, construction and transport vehicles. In fact, all commercial aircraft in North America are required by FAA (Federal Aviation Administration) to have high purity nitrogen in their tires.

Nitrogen is a safe, inert, dry gas and compared to oxygen is a much larger molecule. That size advantage is what decreases the rate nitrogen diffuses/seeps through the tire wall, an issue that leads to lower tire pressure (lost compressed air pressure can average up to 2 PSI per month). Another characteristic of nitrogen versus oxygen is that it less susceptible to temperature changes. With environmental temperture fluctuations and changes in tire temperature during driving, nitrogen is able to run cooler and more consistent helping maintain a specific tire pressure longer.


Nitrogen filled tires stay inflated almost 4 times longer than compressed air filled tires. When tires leak less, they stay properly inflated longer, preventing premature tire wear.  Reducing premature tire wear helps tires last longer, reducing the number of tire replacements required over a vehicle's life and saving you money.  Interesting statistic: 23% of vehicles have at least one tire under-inflated by more than 20% (and the difference can be difficult to notice).


Compressed air traditionally used to inflate tires contains significant amounts of oxygen and moisture. Oxygen reacts with and breaks down rubber (long-term, sometimes seen as cracks in the tread), causing increased air permeation and reduced tire pressure.  In addition, oxygen's moisture can attack and weaken the steel cords in the tire through corrosion. Since temperature changes cause regular air to expand and contract more than Nitrogen, tire pressures can change drastically. As temperature drops so does tire pressure (something people rarely check), resulting in: dangerous under inflation, loss of handling, increased stopping distance, reduced traction and overall decreased safety.



Keeping your tires within the recommended pressure range can have significant impacts on improved fuel economy. To see how much fuel you can save driving on nitrogen filled tires, try the fuel calculator (be sure to adjust to kms for a more appropriate reading)

"
Under-inflated tires increase fuel consumption."
Transport Canada

"Operating a vehicle with just one tire under-inflated by 56 KPa (8 psi) can reduce the life of the tire by 15,000 km and can increase the vehicle's fuel consumption by 4%."
Government of Canada

 

In North America, over 7 million litres of fuel is wasted each day due to vehicles driven on under inflated tires. Nitrogen improves fuel efficiency by up to 4% and also reduces carbon emissions. For every one litre of fuel saved, approximately 5 pounds of carbon dioxide is not released into the air we breathe.  When tires last longer, less replacements are required and fewer tires ultimately 
end up in landfills.
