Core Test Items:
The motor drives the tire to rotate at a constant speed. The laser sensor synchronously scans the tread circumference (for roundness measurement) and sidewall (for run‑out measurement). The software collects distance data in real time, calculates deviations from the reference circle, plots curves and performs analysis. Upon test completion, data is automatically saved and reports are generated.
