How frequently should vehicle owners check their tire pressure to help with emissions?

Regularly checking tire pressure is crucial for vehicle maintenance and can significantly impact emissions. Monthly checks are recommended because tire pressure can fluctuate due to temperature changes and the natural loss of air over time. Maintaining the correct tire pressure helps ensure that the vehicle operates efficiently, which can lead to reduced fuel consumption and, consequently, lower emissions. Underinflated tires can cause the engine to work harder, increasing greenhouse gas emissions and other pollutants.

By making it a habit to check tire pressure at least once a month, vehicle owners can prevent issues that arise from improper inflation, promoting better fuel efficiency and environmental performance.
