KPI – Tyre Torque Compliance

Tyre Torque compliance is a measure of the compliance of a suspension system when subject to a tyre self aligning torque. Tyre torque compliance is measured in Degrees of toe change per Kilo-Newton Metre of tyre torque compliance (Deg/kNm).

This metric can be though of as a measure of the sensitivity of the suspension system to changes in tyre pneumatic trail. As a vehicle corners and the tyre pneumatic trail changes, a suspension system with high tyre torque compliance will deliver unwanted toe change.

Production vehicles would typically have tyre aligning torque compliance values between 0.5 Deg/kNm – 1.5 Deg/kNm.
