A tire wear state estimation system for a tire calculates tire effective radius during measured distance intervals travelled by the tire from vehicle speed and tire rotation counters. The system includes a filter for selecting slow-speed effective radius measuring intervals and an estimator for estimating the tire effective radius during only those intervals in which the vehicle is travelling below a threshold speed.
