During extreme summer heatwaves, what is the correct and safe procedure for managing heavy truck tire pressure increases during long-distance highway hauling?

1. Park in a shaded service area and allow the tires to cool down naturally; NEVER deflate hot tires or pour cold water directly onto hot tires
2. Immediately bleed air from hot tires until the pressure drops below the winter cold specification
3. Pour cold water continuously over the hot brake drums and tires while driving
4. Increase highway speed to 120 km/h so that airflow cools the tire tread surface
