Proper tire maintenance is crucial for the fuel efficiency of heavy-duty trucks. Under-inflated or worn-out tires create greater rolling resistance, forcing the engine to work harder and consume more fuel. Ensuring that tires are properly inflated and regularly inspected for wear can significantly improve fuel economy. Fleet operators should also consider using low rolling-resistance tires, which are specifically designed to minimize the energy required to keep the truck moving. These tires are especially useful for heavy-duty trucks carrying large cargo over long distances, where small improvements in efficiency can translate into substantial fuel savings.

The advent of electronic fuel injection (EFI) systems in the late 20th century marked a significant turning point in automotive engineering. EFI systems replaced carburetors by using sensors and computer controls to optimize the air-fuel mixture in real-time. This technological shift offered numerous advantages improved fuel efficiency, enhanced performance, and lower emissions. Consequently, carburetor engines began to fall out of favor, and newer vehicles predominantly adopted fuel injection systems.
