Systems and methods of buffing tire casings are provided. A tire buffing machine includes a tire hub assembly selectively rotating a mounted casing, a buffer configured to buff the casing, a tire belt detection apparatus having two or more sensors to detect a first belt depth of one or more belts at a first lateral position in a tire casing and a second belt depth of the one or more belts at a second lateral position within the tire casing, and an electronic controller. The controller determines the first belt depth and the second belt depth using a belt detection apparatus having two or more sensors of the belt detection apparatus and adjusts the operation of the buffer based on the first belt depth or the second belt depth.
