As urban areas around the world grow increasingly louder, traffic noise has emerged as a critical environmental and public health challenge. Recognised by health authorities as a major risk factor, this pervasive issue extends from European cities to megacities across Asia and Latin America. Continental is addressing this problem by pioneering tyre technologies that significantly reduce rolling noise, thereby contributing to quieter urban environments and enhanced in-vehicle comfort.

The transition to electric mobility has brought tyre noise into sharper focus. With the near-silent operation of electric motors replacing traditional engine sounds, the acoustic contribution from tyres becomes far more prominent, even at moderate city driving speeds. In response, Continental engineers have developed specialised solutions that target noise generation without compromising the safety, durability or performance of the tyre.

One such innovation is the Silent Pattern tread design, featured on models like the EcoContact 7. This technology disrupts the conventional, uniform arrangement of tread blocks that typically creates a rhythmic humming sound on pavement. By intelligently varying the spacing and angles of these blocks, the pattern breaks up this acoustic consistency. Furthermore, it is tuned to cancel out specific sound frequencies, akin to the principle behind noise-cancelling headphones. This results in a measurable reduction of traffic noise at speeds around 50 kmph, where rolling noise is most perceptible to pedestrians and residents.

For reducing noise inside the vehicle cabin, Continental employs its ContiSilent technology. This involves lining the inside of the tyre with a lightweight polyurethane foam that absorbs vibrations caused by the tyre’s contact with the road. By dampening these air vibrations, the technology can cut perceived in-cabin rolling noise by up to nine decibels – a reduction the human ear experiences as nearly halving the volume. This substantial increase in acoustic comfort is integrated into various product lines, including high-performance summer tyres, without affecting driving dynamics or efficiency.

The company’s commitment to low-noise mobility spans multiple vehicle segments. From the Conti Urban NXT for city buses to passenger car tyres like the EcoContact 6 Q and van tyres such as the VanContact A/S Eco, these products are designed to meet stringent noise standards. Consumers can readily identify these quieter options through regulatory labels, like the EU tyre label, which provides clear decibel ratings for external rolling noise. Through these continuous advancements in tread design and sound-dampening materials, Continental is systematically working to diminish the acoustic footprint of road traffic.

According to Achillefs Tsotras, head of Continental’s Tyre-Vehicle Interaction department, “Noise, especially traffic noise from cars, buses and delivery vehicles, is a major burden for people and the environment. With tyre technologies like ContiSilent and innovative tread designs, we are actively reducing rolling noise without compromising safety. This makes every ride noticeably quieter, benefiting drivers, pedestrians, residents and the environment alike.”

The Yokohama Rubber Co., Ltd. developed a proprietary tyre mould design support system in April 2026, integrating finite element method (FEM) simulations and the company’s own artificial intelligence technology. This new tool is designed to augment the expertise of development personnel, enabling even less experienced staff to efficiently design moulds. It achieves this by providing data derived from numerous virtual experiments, which clarify how different mould design factors influence tyre characteristics.

The system accelerates mould development, lowers costs and minimises the rework typically associated with realising new designs. Furthermore, by fostering a multi-perspective understanding of the links between mould design elements and tyre performance, the tool equips Yokohama Rubber’s developers with fresh insights. These discoveries are expected to aid in creating tyres capable of achieving higher performance levels.

Developed under Yokohama Rubber’s HAICoLab AI concept launched in October 2020, the system addresses longstanding challenges. Mould design critically affects tyre traits, but traditionally understanding this relationship required expensive, time-consuming trial production and evaluations. The process also depended heavily on the tacit know-how of highly experienced staff, leading to variations in accuracy and development time based on individual expertise.

The support system resolves these issues through automated simulations and AI-based prediction and visualisation. It first generates numerous tyre FEM models with varied mould shapes and calculates their characteristics in a virtual space. These results train an AI surrogate model that instantly predicts design factor-performance relationships. By applying explainable AI technologies like SHAP and Partial Dependence Plots, the company’s developers can quantitatively visualise each factor’s impact, easily determining necessary adjustments to achieve targeted tyre characteristics.
