The tires of a car support the weight of a stationary car. If one tire has a slow leak, the air pressure within the tire will _______ with time, the surface area between the tire and the road will ________ with time, and the net force the tire exerts on the road will ___________ with time.
i know it decrease,increase and remain constant but can someone tell me why it remain constant please.

reduce, increase, constant
