Why is proper tire inflation important for emissions?

Proper tire inflation is crucial for emissions because adequately inflated tires significantly enhance fuel efficiency. When tires are under-inflated, they create increased rolling resistance, meaning that the engine must work harder to maintain speed. This extra effort leads to higher fuel consumption, which in turn increases the amount of carbon dioxide and other pollutants emitted into the atmosphere. Conversely, properly inflated tires ensure that the vehicle operates efficiently, consuming less fuel and, consequently, generating fewer emissions. This relationship illustrates why maintaining the correct tire pressure is essential not only for vehicle performance but also for environmental impact.
