The adhesion of rubber compounds to brass‐plated steel cords is particularly significant in radial tires. Xinyan Shi et al. summarize the advantages and disadvantages of existing test methods, and introduce a novel testing technique for the dynamic adhesion of rubber/steel cords. The surfaces of “pulled‐out” steel cords are examined by stereoscopic zoom microscope. Before and after fatigue, the covered rubber on the pulled‐out cords forms a “screw thread” form; while the greatest pulled‐out force corresponds to clearer, more uniform, screw‐like rubber coverage with finer screw threads. The cover image shows micrographs of rubber coverage on pulled‐out steel cords. The new method is very simple, reliable, and does not require extra capital investment. DOI: 10.1002/app.39460
