Tire profile generating machine and related methods

A process for removing material from a tire comprising:

• providing at least one grinding assembly having a grinding head with at least one grindstone rotatably supported thereon, said grinding head being movable axially and radially relative to the tire;
• providing actuators operatively connected to said grinding assembly to move the grinding head;
• providing a controller in communication with said actuators and at least one sensor that monitors operation of said grinding head;
• and
• profiling the tire by contacting said grindstone to the tire to remove material from the tire and adjusting the position of said grindstone while it is in contact with said tire to define a selected profile by grinding a tire to match a profile stored in the system controller, wherein said controller uses the stored profile to create signals sent to the actuators to move the grinding head to a series of selected positions creating the selected profile.
