Correct answer
Improves safety and helps reduce fuel use
The vehicle manufacturer’s recommended pressure helps maintain safety and avoids increased consumption from underinflation. Check it cold and adjust for load and the instructions for each axle. Do not automatically target the tyre-sidewall maximum; correct pressure does not guarantee avoiding every loss of grip. It matters on both short and long journeys.
