A system for leak testing an envelope for a tire assembly can include a rim, an envelope sized to accommodate a green tire assembly and secured to the rim, a vacuum system in fluid communication with the envelope, and a controller. The controller can be configured to pressurize the envelope to a predetermined pressure, compare a slope of pressure over time to a predetermined value, and enable proceeding with a depressurization of the envelope responsive to determining the slope of the pressure over time being more than or equal to the predetermined value.
