Title
(EN) Method of testing rubber wear, and method, device and program of calculating rubber index of tire using method of testing rubber wear
Abstract
(EN)

Provided is a method of testing rubber wear in which a wear phenomenon occurred in a tire can be precisely reproduced in a sample, and a method of calculating the rubber index of a tire using the method of testing rubber wear.

Also provided is a test method for predicting the anti-wear properties of a tire by using a test piece of the same rubber as that of a tire tread, which is a method of testing rubber wear in which, while a disk-shaped sample 3 and a disk-shaped grinding wheel 1 are rotated at individually predetermined numbers of rotations, the sample 3 is pressed on the outer periphery of the grinding wheel 1. A pressing load is applied to the sample 3 such that a contact pressure when the sample is pressed on the outer periphery of the grinding wheel 1 and a contact pressure at a site related to the evaluation of rubber wear of tread are the same.
