Improved Fuel Economy

Low Pressure in tires leads to increased friction and a lower MPG. A recent study by the US Department of Energy was carried out to ascertain the impact of low tire pressures vehicles.

  • 3.56 million gallons of gas are wasted each day because of incorrectly-inflated tires.
  • You can improve your gas mileage by around 3.3 percent by keeping your tires inflated to the proper pressure.
  • For every pound per square inch that all four of a vehicle's tires are under-inflated, a driver’s gas mileage is lowered by 0.4 percent.
  • Proper air pressure results in better gas mileage, which at $3 per gallon could save you as much as $432 per year.

Within the automotive world there is a significant amount of data which outlines gains across the various components of a vehicle. Very little information regarding fuel economy and low tire pressure was in place. The advent of more fuel efficient vehicles now being manufactured across the world has lead to gains also being see with tires at the correct pressure.
