What happens if you drive with too low air pressure in the tires?
Fuel consumption increases, tires wear out faster and the car has poorer road grip.
Fuel consumption decreases and tires last longer.
Nothing happens, too low pressure is better for economical driving.
Explanation
Too low air pressure in the tires makes the rolling resistance increase, which raises fuel consumption and gives poorer grip, while the tires wear out faster.
