What effect can poor tire pressure have on vehicle emissions?

Poor tire pressure can significantly impact vehicle emissions primarily because it leads to increased fuel consumption. When tires are not properly inflated, the rolling resistance of the tires is higher, which means that the engine has to work harder to move the vehicle. This increased effort results in higher fuel usage, since the engine burns more fuel to maintain speed and power.

As fuel consumption rises, it produces more exhaust emissions, including pollutants such as carbon monoxide, nitrogen oxides, and particulate matter. Thus, maintaining the correct tire pressure is crucial not only for improving fuel efficiency but also for minimizing the overall emissions produced by the vehicle. This creates a direct link between tire maintenance practices and environmental impact, making it essential for vehicle owners to regularly check and adjust tire pressure to ensure optimal performance and reduced emissions.
