Apparatus for measuring the tire parameters of a tire carcass supported on a drum including a sensor member disposed above the drum and movable up and down toward the drum by a carriage unit. A length of chain extends from one side of the drum about a chain sprocket carried on the lower end of the sensor member to the carriage unit where its end is coupled to a slack takeup device. When the carriage unit is moved downwardly until the sensor member engages the tire carcass, the chain is displaced by virtue of its engagement with the tire carcass and this displacement is measured by a measuring device carried by the carriage unit to indicate the bead-to-bead length of the tire carcass. Also, a second measuring device carried by the carriage unit measures the distance between the center of the drum and the point of engagement of the sensor member with the crown of the tire carcass to measure the outside diameter of the tire carcass.
