1. A tire changer machine for changing a tire on a wheel rim, the machine comprising:
- a base;
a drive assembly coupled to the base and configured to rotate the wheel rim and tire about a rotational axis;
at least one tool configured to engage the tire in a tire change procedure;
a rotational position sensor providing a signal indicative of a rotational position of the wheel rim and tire; and
a controller operatively coupled to the drive assembly and the at least one tool;
wherein the controller is configured to;
monitor the signal and a corresponding rotational position of at least one designated feature of the wheel rim or tire during a tire change procedure; and
while the wheel rim and tire are rotated about the rotational axis in the tire change procedure, adjust a position of the at least one tool in response to the rotational position of the at least one designated feature.

Abstract
A tire changer machine includes a control system that monitors a rotational position of a sensitive feature associated with a wheel rim and tire during a tire change procedure. The system adjusts operation of the machine to avoid damaging the sensitive feature, which may be a valve stem or a wheel sensor such as a tire pressure monitoring system (TPMS) sensor.

20. A method of performing a tire change procedure utilizing a tire changer machine including a base, a drive assembly coupled to the base and configured to rotate a wheel rim and associated tire about a rotational axis, at least one tool configured to engage the tire in the tire change procedure, a rotational position sensor providing a signal indicative of a rotational position of the wheel rim and associated tire about the rotational axis, and a controller responsive to said signal, the method being executable by the controller and comprising:
-
accepting a reference input corresponding to a designated feature associated with the wheel rim or tire; and operating the machine to avoid a positional conflict between the designated feature and the at least one tool by adjusting a position of the at least one tool in response to the signal as the at least one designated feature is rotated proximate the tool during rotation of the wheel rim and tire about the rotational axis. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
