A computer-implemented method for calculating a wear rate of a tire, the method comprising: providing an aggregation of residual tread depth, RTD, assessments based at least in part on data obtained from at least one sensor attached to at least one tire of a vehicle; generating a mathematical model of the tire wear rate based at least in part on the provided aggregation of RTD assessments; and calculating the tire wear rate based at least in part on the generated mathematical model of the tire wear rate.
