The adhesion layer at the steel cord/ rubber interface has received considerable attention for improving the adhesion performance and stability of automobile tires. For brass-plated steel cord, many studies have been carried out on the adhesion and cord/rubber interface for the last several decades. However, the adhesion and interface of bronze-plated steel cord (bead wire) have been less investigated. In order to understand the nature of bead wire/ rubber adhesion, characterization of bead wire/rubber interfacial structure is critical. A new non-contact method to analyze the adhesion layer of bead wire/rubber interface for auto tires is introduced in this paper. The advantage of this new method lies in a simplicity and feasibility for obtaining a clean adhesion interface by simply removing the rubber compound placed at a small distance apart from the bead wire after the vulcanization process. As the tin content of bead wire for two different rubbers was increased, both interface morphologies became bigger, but the interface morphology for the tested rubbers was different. The difference of interface morphology was originated from the difference in the sulfide composite of gas evaporated from the rubber compound.
