Inflating tires correctly is essential to ensure safety, fuel economy, and tire service life. Incorrect pressure can compromise vehicle performance and increase the risk of accidents. This guide explains how to adjust tire pressure accurately and the precautions needed to keep tires in ideal condition.
Consequences of Incorrect Tire Pressure
Incorrect tire pressure can cause increased fuel consumption (up to 20% in extreme cases), uneven tire wear, and reduced grip during cornering and braking.
Practical Tips for Inflating Tires
Always use the pressure recommended by the manufacturer, check pressure when the tires are cold, and inspect for cuts, bulges, and uneven wear while adjusting tire pressure.
