Continental product chief on putting customer needs at the heart of tyre development
Continental’s truck and bus tyre portfolio spans a wide range of applications, each with its own demands. From long-haul and regional transport to construction, urban buses and coaches, tyres need to deliver the right balance of performance for the job.
Understanding those requirements is a key part of Continental’s product development process, with direct feedback from OEMs and fleets helping to shape products alongside advances in technology and changing regulations.
Hinnerk Kaiser, head of product development for bus and truck tyres at Continental, spoke to CV Workshop Magazine about how this customer-led approach works:
CVW: How does Continental approach the process of developing a new tyre?
HK: The development of a new tyre begins with understanding how it will be used. Feedback from OEMs and fleets provides valuable insight into the challenges operators face and the characteristics they need from a tyre.
These requirements are then carried through the development process, from simulation and technology development to prototype production and field testing. This allows Continental to assess how a tyre performs in real operating conditions, rather than relying solely on laboratory results.
CVW: How are Continental’s TBR tyres tailored to different operating conditions?
HK: Commercial vehicles operate in very different environments, making application-specific development essential. Factors such as mileage, durability, rolling resistance and operating conditions all influence the design of a tyre.
Continental’s truck portfolio reflects this variety, with products such as the Conti EfficientPro and Conti Hybrid families developed to meet the differing requirements of long-haul and regional operations, alongside solutions for more demanding applications.
The same principle applies to buses. Urban buses experience frequent acceleration, braking and kerb contact, while coaches typically prioritise high mileage, durability and low noise. Products including the Conti Urban and Conti Coach ranges are designed around these distinct requirements.
CVW: How do material choices and structural design influence tyre performance?
HK: The choice of materials and construction used in a tyre also plays an important role. Different combinations of rubber, steel reinforcement and other materials can be adapted to suit the stresses associated with each specific application.
This extends to individual components such as the belt, bead and sidewall. The Generation 5 Conti Urban, for example, features a redesigned sidewall with thicker material to provide additional reinforcement against the demands of repeated kerb contact.
Sidewall indicators also help operators identify abrasion resulting from kerb impacts, providing a useful visual reference for monitoring tyre condition. With Generation 5 now established across the portfolio, Continental is already looking ahead to the next stage, with development of Generation 6 underway.
CVW: What role did the Generation 5 play in balancing on-the-road performance?
HK: A major consideration when developing commercial vehicle tyres is the relationship between rolling resistance, mileage and wet grip – Continental’s ‘magic triangle’.
Improving one characteristic has traditionally involved compromises elsewhere, but advances in compounds and materials are helping to broaden what is possible. Continental’s Generation 5 range, for example, introduced a real silica tread compound developed to support performance across several key characteristics.
CVW: How does Continental approach the full lifecycle of a tyre beyond its initial use?
HK: For Continental, tyre development does not end when a product is fitted to a vehicle. The wider lifecycle of the tyre is also considered from the outset.
Retreadability is an important part of this, with casing durability and robustness considered alongside the performance requirements of the original tyre. Since development takes into account the potential for further service lives, Continental can design products with their wider lifecycle in mind.
Ultimately, it is this combination of direct customer input, technological development and application-specific engineering that continues to shape Continental’s truck and bus tyre portfolio. All of which help Continental continue to develop products in line with the changing demands of commercial vehicle operators.
