Tire wear estimation

A tire wear estimator, comprising a tire measurement system which is adapted to be mounted in a tire or on an inner surface of a tire, the tire measurement system comprising a sensor adapted for sensing a physical property of the tire, and an acquisition system adapted for sampling a signal of the sensor into memory to acquire a perturbation in the sampled data which is induced by a contact patch of the tire when a part of the tire where the sensor is mounted hits the ground, wherein the sensor is an acceleration sensor adapted for measuring radial acceleration and/or for measuring tangential acceleration and wherein the acquisition system is adapted for sampling at a sample rate that allows at least one oscillation, which has a characteristic frequency of 200 Hz or more, which is indicative of a tread depth of the tire, to become detectable in the sampled data in and/or around the perturbation, wherein the sample rate is at least 400 samples per second.
