This machine tests the stiffness uniformity of a pneumatic tire body by rotating it while in place on a vehicle and resting on the tester, and recording vertical tire deflections (weak spots or hard spots) on a chart. The tester has a base frame with drive roller, an adapter carried by the tire wheel at its rim and holding a chart, a motion pickup linkage in touch with an axle of the adapter, and a scribe actuated by the linkage and bearing against the chart.
