Rolling Resistance Evaluations
Fuel prices and greater awareness about the role tires have in improving fuel economy
has created renewed interest in tire rolling resistance evaluations. A tire’s rolling resistance impacts on fuel economy through a combination of heat loss, aerodynamic drag and the friction between tires and road surfaces. Rolling resistance can be performed on the following tire types:
- Passenger and light truck
- Medium-duty truck
- Super single truck
- Dual assemblies
- Tow motor
Industry Standards for Rolling Resistance Testing
- SAE J1269
- SAE J2452
- ISO 8767:1992
Certification & Accreditation
Smithers’ tire testing laboratories in Ravenna, Ohio and Suzhou, China are correlated for the measurement of tire rolling resistance with the Global Network of Reference Laboratories, as defined in (EC) No 1222/2009. This alignment allows clients to report rolling resistance data for the purposes of EU tire labeling requirements - UNECE Regulation No. 117 (R117).
All Smithers laboratories are ISO 17025 accredited.
