Tire design and engineering considerations (tread pattern, sidewall design)

The tire design process at Sumitomo involves a harmonious blend of artistry and engineering prowess. Expert designers meticulously craft each aspect of the tire’s appearance while considering crucial performance factors such as traction, handling capabilities, hydroplaning resistance, and noise reduction.

The tread pattern plays a vital role in determining how effectively a Sumitomo Tire grips various surfaces. Extensive research goes into developing innovative tread designs that optimize traction on both wet and dry roads while efficiently dispersing water or snow from the contact patch.

This intricate pattern also contributes to reducing road noise levels for an enhanced driving experience. Sidewall design is another crucial element that showcases Sumitomo’s commitment to excellence in every aspect of their tires’ aesthetics and functionality.

The sidewalls not only represent an opportunity for branding and visual appeal but also provide important information such as tire size, load index, and speed rating. Sumitomo carefully considers the sidewall design to ensure it complements the overall tire appearance while meeting the necessary safety requirements.

Production stages – from mixing compounds to curing the tires

Sumitomo Tires undergo a meticulous production process that involves several stages, each critical to achieving optimal performance and durability. Let us delve into these stages, starting from compounding and mixing.

1) Compounding and mixing process for rubber compounds: The rubber compounds used in Sumitomo Tires are created by precisely blending various raw materials with specific additives.

This process involves careful measurement of ingredients to achieve desired characteristics such as flexibility, heat resistance, and durability. Advanced machinery ensures thorough mixing and homogeneity of the rubber compound before proceeding to the next stage.

2) Tire building process – layers, belts, and sidewalls assembly: Sumitomo employs advanced tire-building machines operated by skilled technicians in this crucial stage.

Beginning with a drum-shaped core known as a “building drum,” multiple layers of different materials are applied according to precise specifications. These layers include steel belts for reinforcement, fabric plies for stability, and sidewalls for structural integrity.

A complex computer-controlled system ensures precision in layer application, guaranteeing uniformity across all tires produced. 3) Vulcanization – shaping and curing the tires under heat and pressure:

Vulcanization is a transformative process where raw tires are shaped into their final form while acquiring their most essential properties. The green tire is placed in a mold that determines its tread pattern and sidewall design.

Heat is then applied under controlled pressure within giant curing presses. This process chemically bonds various components together while simultaneously imparting elasticity, strength, resilience, and other critical characteristics that enable Sumitomo Tires to perform optimally on the road.

These meticulous manufacturing processes exemplify Sumitomo’s commitment to precision and quality at every stage of tire production.
