Under inflation is one of the leading cause of Tyre failures.
According to government statistics, 90 percent of all Tyre failures are a result of under inflation, primarily due to the buildup of internal heat under inflation generates. Underinflated Tyres over heat because they can’t maintain their proper shape, becoming flatter than intended while in contact with the road. Tyres that are under inflated by just a few pounds can suffer from a weakening of their internal structure and quickly fail.
2) Tyre Wear
Under inflated Tyres wear much faster than properly inflated ones because low air pressure distorts a Tyre’s shape and the way it contacts the pavement, typically grinding the tread off of the sides of the Tyre’s treaded contact area. But filling your Tyres with Nitrogen will greatly increase the life of your Tyres.
3) Fuel Savings
This is reason enough and about as serious as it gets. Australia alone waste over 2 million liters of fuel EACH DAY due to under inflated Tyres. Under inflated Tyres wear out faster, fail much more frequently and have a detrimental impact on a vehicle’s fuel economy.
This distortion also increases “rolling resistance,” the culprit behind the devastating effect low Tyre inflation can have on a vehicle’s fuel economy. Potentially a lot more, as studies show that under inflated Tyres can diminish fuel economy by up to 10%.
4) Tyre Pressure Stability
Running your Tyres at a pressure that is just 10% below their preferred pressure setting, typically just 3 – 4 psi, can diminish their usable life by 25%.
Essentially, it takes more energy to propel a vehicle with under inflated Tyres. If you have ever ridden a bicycle or had the misfortune of pushing a car with under inflated Tyres, you get it, it takes more effort to propel a vehicle with Tyres that are low on pressure. The air we breathe and use to inflate Tyres chemically consists of 78% nitrogen, 20 % oxygen, and 2% other.
When using nitrogen as an inflation gas, the composition of nitrogen increases from 79% to near 100%. Michelin, Bridgestone and Dunlop all support the use of nitrogen, based on its ability to better retain air over a period of time and will continue to warranty their products with its continued use.
