Why Is Fuel Efficiency at Risk with Low Tire Pressure?
Fuel efficiency is at risk with low tire pressure because under-inflated tires increase rolling resistance. This higher resistance causes the engine to work harder, leading to greater fuel consumption.
The National Highway Traffic Safety Administration (NHTSA) defines rolling resistance as the force that opposes the motion of a tire as it rolls down the road. Proper tire pressure is crucial for minimizing this resistance and ensuring optimal fuel efficiency.
The underlying causes of reduced fuel efficiency due to low tire pressure include the deformation of the tire shape and increased contact area with the road. When tires are not inflated to their recommended levels, they become flatter and wider. This change leads to more rubber touching the road surface, increasing the energy needed to move the vehicle forward.
Rolling resistance, in technical terms, refers to the energy loss due to the deformation of the tire as it rolls. The tires flex more at lower pressures, which generates heat and absorbs energy that could otherwise be used for propulsion. Additionally, decreased pressure can lead to uneven tire wear, further exacerbating the issue.
Specific conditions that contribute to low tire pressure include environmental factors, such as temperature changes, and neglecting regular tire maintenance. For example, tires lose air pressure as temperatures drop—approximately 1 PSI for every 10°F decrease. Drivers who do not frequently check and maintain their tire pressure may experience diminished fuel efficiency.
In scenarios where a vehicle is driven with tires under-inflated, drivers may notice a decrease in fuel economy. For instance, if a vehicle’s tires are 15% under the recommended pressure, it could reduce fuel efficiency by up to 6%. Therefore, maintaining proper tire pressure is essential for preserving fuel efficiency and ensuring safe driving conditions.
