Vastly improved fuel economy...

Tyre & Economy Facts

• Motoring safety authorities estimate that 25% of Australian vehicles are running on underinflated tyres and over 40% have not checked them in the last 6 months.
• Properly inflated tyres run cooler, last longer, and improve fuel economy.
• There is a 1% reduction in fuel economy for every 3 PSI (pounds per square inch) under inflation (checkmytires.org).
• Properly inflated tyres translate to a free tank of petrol every year.
• A vehicle whose tires are 7 PSI below the recommened level will have increased its rolling resistance by 12.5%. (Source: Department of Energy)
• Changes in the weather affect tyre pressure - Tyre pressure changes an average of 1 PSI (pounds per square inch) for every 5°C change in air temperature (checkmytires.org).
• The US Energy Department stated that under-inflated tyres wasted an estimated 15 million litres of petrol every day in America in 1995. (Source: pumpmeup.org)
