Over the last century, the world population has more than quadrupled. [1] Most of this growth is centred around the Asia-Pacific region, which is estimated to drive 40 per cent of the world’s consumption of goods and services by 2040. [2] In the last 30 years alone, countries such as China and Vietnam have experienced rapid urbanisation, fuelling economic growth and opening doors to infrastructure and public services to address the needs of the ever-rising middle-class population.

As people move up the economic ladder, their desire to lead a more comfortable life has a significant impact on many industries, including the automotive sector. The region’s economic potential and growing appetite for luxury and environmentally friendly products have led to innovations in the areas of Connected, Autonomous, Shared and Electric (CASE).

Vehicles, which play a huge role in the mobility of people and goods in this part of the world. And as critical components of automobiles, the tyre industry must keep pace with the changes brought about by CASE. The future of tyre will need to bring continued reliability, safety, and enhanced performance yet have the ability to integrate emerging technologies such as sensors, smart diagnostics and advanced safety systems. Such changes are also driving tire companies to innovate and develop diversified products and solutions as we move towards the concept of Mobilityas-a-Service (MaaS). 

EV tyres 
For instance, electric vehicles tend to be heavier due to the extra weight of the battery pack. Tyres for electric cars thus need to be structurally reinforced to withstand this increased load while maintaining low rolling resistance to maximise fuel efficiency. Conscious of consumer’s changing preferences and the associated environmental benefits of electric vehicles, Bridgestone specially designed custom-built tyres i.e. the ECOPIA ologic series for the BMW i3 electric vehicles. The tyres feature narrow tyre width to realise low rolling resistance and to reduce aero-dynamic resistance which are important factors in the improvement of a vehicle’s fuel efficiency and the reduction of carbon emissions.
 Another trend in the automotive industry that has influenced the design of tyre is the rise of “shared mobility” services, such as ride-sharing. In the last few years, we have witnessed the massive popularity of ride-sharing platforms, and this growth is only projected to increase. A recent report by Bizwit Research estimates that the ride-sharing industry will grow by more than 20% between the years 2019 to 2025 [3].

 Run-Flat Technology 
On this front, Bridgestone’s tyres are engineered to offer enhanced performance and durability as the road-life of the tyres need to withstand the high-frequency usage demand of these vehicles. Solutions such as the recently launched DriveGuard RunFlat Technology (RFT) enable drivers to remain in control and continue driving up to a maximum distance of 80 kilometres at a maximum speed of 80 kilometres per hour after a puncture or complete loss of pressure. In addition to this, Bridgestone’s automatic sealant technology called B-Seal also guarantees air retention when nails, stones or other objects are embedded at up to 5mm in diameter in the tyre tread. These tyre solutions focus on extending tyre endurance and mobility - ideal for vehicles used very frequently in the ride sharing scenario. The rise of IoT and AI technologies is also powering the evolution of connected and autonomous selfdriving vehicles. Selfdriving opens up a world of possibilities - from increased personal safety to time efficiency and mobility for non drivers. In Asia, China seems to be taking the lead in readying self-driving vehicles for production, expecting fully autonomous vehicles to account for 10 per cent of car sales by 2030.[4] This accelerating transformation towards autonomous operations has a significant impact on the tyre industry. Tyre manufacturers will need to work towards creating tyres that can communicate with these autonomous vehicles, involving the integration of advanced sensor technologies, smart diagnostics and data analytics. 
Having identified these needs at an early stage, Bridgestone is transforming its business operations to focus on solutions and integrating these technologies to meet the needs and expectations of the next generation of drivers. At its foundation is the newly introduced global mobility solutions strategy called Bridgestone Tires & Diversified Products as a Solution (Bridgestone T&DPaaS). The strategy is a combination of products, services such as Bridgestone’s Global Service Network and digital technologies.

Smart Strain Sensor
Under the digital techniques branch, Bridgestone has developed a new type of tyre sensor, called the Smart Strain Sensor. A first-of-its-kind, the Smart Strain Sensor technology incorporates Internet of Things (IoT) technologies to help measure the strain that occurs when a tire makes contact with the road while in motion. Furthermore, unlike accelerometer sensors, the Smart Strain Sensor can record data even at low speeds, which makes it an important differentiator for autonomous vehicles which are expected to operate at lower speeds for enhanced safety. Last year, Bridgestone also acquired TomTom Telematics, now renamed as Webfleet Solutions, which offers 
data-based solutions that make fleet operations more effective and efficient. Through this, Bridgestone gains valuable insights into vehicle and tire operating conditions from a user base of 860,000 vehicles communicating 200 million data points per day, thus accelerating its tire solutions offerings and paving the road towards autonomous driving. As the automotive industry continues to transform with the ongoing implementation of CASE, it is evident that tires will continue to play a key role in this revolution. However, in order to overcome the challenges and benefit from the opportunities arising from these trends, the tire industry will need to “reinvent the wheel” to stay on track and meet the evolving needs of the wider automotive industry.

Hankook Tire has been chosen as the original equipment manufacturer for the Volkswagen Tiguan and Tayron SUV models, fitting them with its Ventus evo SUV tyre. This partnership covers a wide range of specifications, with six different tyre sizes from 17 to 20 inches available for the immensely popular Tiguan and five sizes for the five or seven-seater Tayron crossover. A key identifier for these specially developed tyres is a circled plus sign on the sidewall, signifying they are built to Volkswagen’s precise standards and are approved for factory installation on new vehicles.

The collaborative development process, centred at the Hankook Tire Technology Center in Hannover, prioritised a harmonious blend of comfort and dynamic performance. A major focus throughout the design phase was achieving the lowest possible noise level. Through meticulous tread design and an innovative compound in the tread material, the Ventus evo SUV attains a noise level below 66 decibels. This performance is crucial, as it helps the overall vehicle meet Volkswagen's strict maximum noise requirement of 68 decibels, significantly enhancing cabin quietness.

Further technical hallmarks of these premium tyres include Opti Pitch and Kerf designs, which work to minimise road noise. The implementation of Dual Pitch technology varies the number of tread blocks on the inner and outer sections of the tyre, a feature that enhances steering precision during cornering while also contributing to a quieter ride. Engineers carefully calibrated the tread height to ensure these acoustic benefits do not come at the expense of critical performance areas such as traction, braking, cornering stability or the tyre’s overall lifespan.

Final validation of the Ventus evo SUV involved rigorous testing that extended beyond laboratory simulations to demanding real-world tracks, including the challenging Nürburgring Nordschleife. This extensive testing protocol confirmed the capabilities of all tyre sizes. Furthermore, Hankook tailored the driving character of the tyres by size; the 17-, 18- and 19-inch variants are engineered for superior comfort, while the 20-inch version offers a distinctly sportier feel. Production for the European market is handled at Hankook’s manufacturing facility in Rácalmás, Hungary.

Klaus Krause, Vice President and Head of Europe Technical Centre at Hankook Tire, said, “The provision of original equipment for the two SUV models Tiguan and Tayron is further proof that the Volkswagen Group considers Hankook Tire one of its top development partners in the tyre sector. We have succeeded in perfectly matching our premium summer tyre, Ventus evo SUV, in every tyre size to the driving characteristics of the two models and achieved our goal of combining the requirements for high comfort over long distances with a sporty character.”
