Tire Testing Methods

The tire testing method concentrates distortion at incisions on sidewalls through assembly, pressure, and axial projections to accurately reproduce sidewall cracks, addressing the challenge of crack reproduction in existing methods.

Abstract

To provide a tire test method that can replicate crack resulting from flaw and fissure, which occurs at a side part.SOLUTION: A tire test method includes a step S1 of performing deterioration treatment to a tire, a step S2 of performing processing treatment to the tire, and a step S3 of making the tire run on a running surface of a running test device. By the processing treatment, a notch is formed in a side part of the tire. A position where the notch is formed is a position of maximum surface distortion where surface distortion caused in the side part of the tire when a load is put on the tire becomes maximum. A protrusion extending in an axial direction of the tire is formed on the running surface of the running test device.SELECTED DRAWING: Figure 2
