As part of a strategic partnership, Continental has developed a highly efficient tire for Renault Group‘s innovation teams with up to 35% lower rolling resistance than required for the EU tire label’s top A rating. For a vehicle with a battery range of 500km, this translates to approximately an additional 30km of range per charge – roughly the distance from Paris to Versailles.

The starting point for the tire was Continental’s EcoContact 7, which was then adapted to Renault Group’s requirements. The tire maker combined a specially modified tread compound with a customized sidewall design and an optimized tire construction.

Michelin has formalized and disclosed details of its universal tire digital twin, which can convert in-vehicle data into actionable insights in real time to make recommendations to the vehicle or its driver. The solution was developed to ensure a safer driving experience by allowing a vehicle to anticipate its behavior and improve performance without requiring input from physical tire sensors.

“Thanks to its universal digital twin, Michelin not only listens to the vehicle; it whispers (words of wisdom) in its ear in real time!” said Philippe Jacquin, Michelin Group executive vice president of research and development and a member of the group executive committee.

Sumitomo Rubber Industries (SRI) has announced plans to open a technical center in western New York to support its design, product testing and innovation activities within the North and South American automotive tire market.

The technical center in Getzville will employ approximately 40 engineers and professionals as part of SRI America (SRIA), a subsidiary of SRI. Ten other employees will be based at SRIA’s test track in Huntsville, Alabama.

The SRIA technical center will support research and development activities for passenger, motorcycle and light truck tires for original equipment manufacturers and replacement market customers. Operations will include technical benchmarking, product design, simulation and analysis, materials development and on-vehicle testing.

rFpro and Siemens Digital Industries Software (Siemens) have jointly developed a simulation capability that integrates Siemens’ Simcenter Tire software with rFpro’s TerrainServer, which provides a millimeter-accurate digital model of the road surface.

The interface enables the MF-Tyre and MF-Swift models in Simcenter Tire to directly interrogate rFpro’s TerrainServer surface data and calculate tire forces and moments for vehicle models. It enables accurate simulations of how a tire interacts with the road, a key requirement in virtual testing for both automotive and motorsport development.

rFpro and Siemens collaborated to ensure reliable performance across desktop, cloud and real-time simulations.

Nexen Tire has established a high-dynamic driving simulator at its central research institute, The Nexen UniverCity, in Seoul, South Korea. The simulator is the first of its kind in the Korean tire industry and is intended to support tire research and development using VR and AI technologies.

The simulator enables testing of acceleration, steering response, braking and other performance metrics in a variety of driving conditions. Nexen Tire said it expects to minimize unnecessary trial and error, reduce prototype production and real vehicle testing and accelerate innovation while cutting costs.

The company also expects the simulator to support faster and more accurate alignment with original equipment (OE) requirements, and strengthen collaboration in developing tires for new concepts and high-performance vehicles.

Bridgestone has invested in a new driver-in-the-loop (DIL) simulator at its EMEA R&D Center near Rome in Italy. Complementing its virtual tire development (VTD) capabilities, the new simulator will enable Bridgestone to combine tire and vehicle simulations with AI technologies.

Bridgestone has used VTD for a decade. Having its own simulator will enable engineers to virtually recreate tire behavior, vehicle interaction and response in various conditions. With the help of AI, this combination supports faster assessment of many design options, accelerating development toward targets.

The new simulator will help Bridgestone boost innovation, increase speed to market and improve development efficiency.

Sumitomo Rubber Industries has developed a new technique to predict noise generated by the combined vibration of tires and vehicles.

This method uses a tire rolling motion simulation and aims to assist both tire and vehicle manufacturers in reducing the noise produced by their products, to improve passenger comfort and simplify development processes by reducing the need for physical prototypes.

The new method simplifies the prediction of road noise performance by coupling the vibration characteristics of the tire and vehicle using the transfer function synthesis method, which is more accessible than sensitive vehicle information. It should also reduce the need for tests with actual vehicles and prototype tires.

Continue reading Sumitomo Rubber Industries develops tire noise prediction technique at Tire Technology International.

The Virtual Tire Lab has been launched by Smithers, a provider of testing, consulting, information and compliance services, and Stackpole Engineering Services, which specializes in tire and vehicle development technology.

Virtual Tire Lab is toolset for analyzing raw data and comparing, contrasting and adjusting virtual tire models for use in design analysis, simulation and model certification.

It uses an annual subscription model to provide clients with access to a library of passenger and light truck tire models, which includes a variety of popular brands, sizes and categories such as all-weather, all-season and EV-specific tires. Further models will be added to the Lab library during the subscription period.

On March 26, the Goodyear Tire & Rubber Company officially opened its simulation center in Luxembourg purposed for tire design and development. This follows the launch of the inaugural center in Akron, Ohio, in 2021.

Outfitted with a DiM250 dynamic driving simulator developed by VI-grade, the center is designed to enhance Goodyear’s collaboration with OEMs and support tire performance through personalized product development.

Back in 2020, Goodyear purchased two driving simulators from VI-grade.

Using a virtual tire development process, the new center will test and validate tire models for vehicle prototypes to enable a speedier production process for tire modifications.

Close collaboration between Goodyear and Maserati has led to development of a bespoke tire for the different versions of the new GranTurismo. Goodyear’s Eagle F1 SuperSport, part of the tire maker’s ultra-ultra-high-performance range, has been developed to suit the characteristics of the new Maserati models, and will be marked with MGT.

Virtual simulation was used to develop the tires for the GranTurismo. This simulation helped reduce the number of prototype tires required, streamlining the design and development process. The move away from multiple iterations of physical prototype tires also improves cost and efficiency, due to the huge amount of data that can be collected using virtual R&D methods.
