Abstract
A method of testing a run-flat tire component is provided. In one exemplary embodiment, the method includes positioning a run-flat component upon a wheel, accelerating the wheel to a predetermined speed, decelerating the wheel to a stop, and determining any rotation of the run-flat component relative to the wheel.
Claims20
A method of testing a support ring used in a wheel assembly, comprising the steps of:
- positioning the support ring upon a wheel rim and noting the relative position of the support ring on the wheel rim;
- accelerating the wheel rim and support ring to a predetermined rotational speed;
- from the predetermined rotational speed, stopping the wheel rim and support ring at controlled deceleration rate;
- and
- determining any relative rotational movement between the support ring and the wheel rim.

A method of testing a run-flat tire component, comprising the steps of:
- mounting the run-flat tire component on a wheel;
- marking the position of said component relative to said wheel;
- rotating said wheel at a selected test speed;
- decelerating said wheel at a determined rate of deceleration;
- and
- determining whether said run-flat tire component has rotated relative to said wheel.
3 more elements
A method for centrifugally testing a run-flat tire component, comprising the steps of:
- mounting a run-flat tire component on a wheel;
- connecting said wheel to rotatable power source;
- placing a first mark on said run-flat tire component, placing a second mark on said wheel, wherein said first mark and said second mark are located adjacent to each other;
- rotating said wheel at a determined speed with said rotatable power source;
- slowing said wheel at a constant rate until said wheel stops rotating;
- and
- determining whether said run-flat tire component has rotated relative to said wheel.
