Rolling Resistance Testing
Smithers laboratories are ISO 17025 accredited and can perform a variety of tire rolling resistance tests on a range of different tire types and at varying temperatures including evaluations in accordance with UNECE R117.
Webinar: Effect of Temperature on Tire Rolling Resistance
Original run date: May 10, 2023 at 9:00 AM EST
Tire rolling resistance (RR) is closely related to overall vehicle fuel economy or range, and it’s common that vehicle manufacturers require tire rolling resistance reduction to help optimize fuel economy/cruising range. Tire rolling resistance measurement requirements for use in consumer tire labeling laws are being released in some countries and districts. Threshold values for tires are being established to achieve energy savings, meet green initiatives, and reduce carbon emissions. Current conventional rolling resistance testing methods only focus on tire performance at an ambient temperature of 24°C or 25°C, but real-world applications span a much broader range of operation.
This 30-45 minute webinar will include a discussion of:
- How the market shift to EVs poses new range challenges
- Overview of foundation for current rolling resistance testing
- Theoretical analysis and experimental methods to explore the rolling resistance of tires at other temperatures
