Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body (such as a tire) rolls on a surface. The primary cause of pneumatic tire rolling resistance is hysteresis. Hysteresis is the time-based dependence of a system’s output on present and past inputs. It has been identified in many other fields, even including economics and biology.
I got to thinking about rolling resistance and hysteresis recently thanks to both the recent Silca Journal entries on the subject but also recent cycling trips I’d been on. The trips had some tough terrain but ultimately make my life easier. Friends, family, and even clients see the (bike) time on the road and think it may negatively impact professional output. But they’re wrong.
