Which term refers to the action of not being able to hold air or liquid, often used in relation to tires?

The term that refers to the action of not being able to hold air or liquid, particularly in the context of tires, is deflation. Deflation specifically indicates a loss of air pressure within a tire, which results in an inability to maintain its designed shape and function. This can happen due to punctures, leaks, or other damages that compromise the tire's integrity.

In contrast, crazing refers to the formation of fine cracks on a surface and is usually associated with materials such as plastics or glass. Degradation relates to the deterioration of material properties over time due to environmental factors or chemical reactions. Deformation involves a change in shape or size due to applied forces or stress but does not directly imply a failure to hold air or liquid.
