ISO 28580 · Force Method · 1.7 m / 2.0 m DrumPrecision drum-type rolling resistance measurement system for passenger car, light truck, commercial vehicle, and motorcycle tyres — compliant with ISO 28580, UN ECE R117, and EU tyre labelling regulations.
Applicable Standards
Rolling Resistance Tester
Fuel Efficiency & EU Tyre Label Compliance — ISO 28580 Force Method
Rolling resistance accounts for 20–30% of passenger vehicle fuel consumption and up to one-third of truck fuel use. A 10% reduction in rolling resistance delivers approximately 1–2% fuel economy improvement and a proportional CO₂ reduction.
The machine presses the tyre against a smooth steel drum rotating at test speed (typically 80 km/h). A precision multi-axis load cell on the tyre spindle directly measures the tangential rolling resistance force — the most accurate method per ISO 28580.
Built-in skim test, temperature correction (to 25 °C), and drum curvature correction (to 2.0 m) ensure internationally comparable results. Software outputs the Rolling Resistance Coefficient (RRC) in N/kN and the corresponding EU fuel efficiency label grade. Known internationally as tire rolling resistance testers, these systems are used by tyre manufacturers and certification labs worldwide.

Capabilities
Precision multi-axis force transducer on the tyre spindle directly measures rolling resistance force (Fx) and radial load (Fz) — the most accurate and widely adopted measurement method.
Precision-machined, dynamically balanced drum meets ISO 28580 requirements. Results automatically corrected to 2.0 m reference diameter for international comparability.
Built-in skim (parasitic loss) test automatically subtracts bearing friction, aerodynamic drag, and transducer losses — isolating true tyre rolling resistance from system losses.
Automatic correction of measured rolling resistance to 25 °C reference temperature and 2.0 m drum diameter per ISO 28580 — ensuring comparable, regulation-ready results.
Software directly outputs the Rolling Resistance Coefficient (RRC) and corresponding EU tyre label fuel efficiency grade (A–E) for C1, C2, and C3 tyre classes.
Pre-configured test recipes for ISO 28580, SAE J1269, SAE J2452, UN ECE R117, and AIS-142 — switch between standards with a single recipe selection.
