Tire Development & Testing

Development and engineering capabilities

Virtual tire development

Our virtual development capabilities utilize cutting-edge modeling technologies that enable comprehensive performance prediction before manufacturing physical prototypes. The process includes generating virtual reference models, creating multiple design variants based on specific KPIs, and evaluating performance through advanced driving simulators.

Advanced modeling technologies

We develop and utilize different types of parametric tire models to meet specific project requirements. 

• MF-TIRE and MF-SWIFT models based on the magic formula provide accurate predictions of performance under steady-state and transient conditions, enabling vehicle integration optimization throughout the entire development process.
• FTire models represent our short wavelength, intermediate frequency tire modeling capability with physical orientation. These parametric models utilize IDIADA's proprietary measurement procedures, combining laboratory and proving ground data to achieve precise and representative tire behavior characterization. FTire models excel in primary and secondary ride comfort simulations, NVH analysis, prediction of road loads on irregularities, vehicle handling studies on flat or uneven roads, and real-time simulations for in-depth vehicle dynamics investigation focusing on chassis and tire performance to enhance driver perception and subjective evaluation.
• CD-TIRE models specialize in belt dynamics and 3D road surface interaction, offering high-frequency analysis and wear prediction capabilities. These models are especially valuable for primary and secondary comfort analysis, NVH studies, and load prediction on road irregularities.

For applications requiring maximum fidelity, our 3D multiphysics models operate up to 250 Hz with real-time simulation capability, integrating thermal dynamics and enabling prediction of complex tire phenomena on a strictly mechanical and thermodynamical basis.

Co-development methodology

We implement a tripartite partnership model that brings together OEM requirements, tire supplier innovation, and our expertise in development and validation. This methodology significantly accelerates the development process while ensuring optimal vehicle integration and compliance with all regulatory requirements.

Advanced simulation and analysis

Our driving simulators integrate real-time tire models with digital twins of our proving grounds, enabling virtual validation of complex behaviors before physical tests. This capability is especially valuable for electric vehicle development, where thermal management and range optimization require specialized analysis.

Testing capabilities

Comprehensive characterization with vehicle

Our objective evaluations range from braking tests on multiple surfaces and adhesion conditions to complete dynamic analysis that evaluates tire efficiency in dry and wet conditions. We perform aquaplaning tests both during acceleration and cornering, and specialized rolling resistance analysis to optimize fuel consumption and electric vehicle range.

NVH tests include interior noise and vibration measurements, pass-by noise analysis according to international regulations, and characterization of tire-surface interaction that affects driving comfort. These analyses are complemented by durability studies through wear programs under real conditions throughout the year.

Electric vehicle specialization

We develop specific methodologies for tire validation on electric vehicles, including performance tests with high instantaneous torque, thermal management system integration, range optimization, and compatibility with regenerative braking systems.

Extreme condition testing

Our capabilities include winter performance evaluation under snow and ice conditions, wet traction and aquaplaning tests, and temperature variation studies that guarantee performance under all climatic conditions. Durability programs utilize our proprietary Driving Severity Number (DSN) methodology to accelerate and faithfully represent wear under real conditions.

Certification and regulatory compliance

As an ISO 17025 accredited laboratory, we provide complete certification services for European regulations, FMVSS, INMETRO, GSO-SASO, and other global standards. Our capabilities include standardized pass-by noise tests, wet grip, and rolling resistance for all tire categories.

Specialized characterization equipment

Applus+ IDIADA's skid trailer enables dynamic characterization under real proving ground conditions with complete control over tire attitude and precise measurement of forces and moments. The system can perform lateral slip, longitudinal slip, combined slip, and cleat tests on different surfaces.
