A tire truing apparatus having a driven tire mounted for longitudinal movement toward and away from a motor driven cutter mounted for movement transversely of the tire along a preselected tread contour forming path. A transversely movable carriage has a cutter motor supporting plate that is pivotally connected to its forward end and is pivoted relative to the carriage by a cam and connecting linkages. A pair of radius rods have first ends pivoted to a frame and have their other ends pivotally connected at preselected positions in arcuate slots formed in the carriage having radii equal to that of the radius rods and transcribed about the axes of said first ends when the carriage is centered transversely. The arcuate extent of the slots is sufficient to allow the radius rods to be adjusted from a divergent position through parallel position and into a plurality of preselected convergent positions for guiding the cutter along preselected paths which will cut transverse contours on the tires, which contours vary from small to progressively larger radii convex curvatures, to a flat cut, and finally to concave curvatures.
