  "textContent": "The invention concerns a tread wear monitoring method comprising a tread wear model calibration step () and a tread wear monitoring step (), wherein the tread wear model calibration step () includes determining () a calibrated tread wear model based on tread-wear-related quantities and first frictional-energy-related quantities. The tread wear monitoring step () includes: acquiring (), from a vehicle bus () of a motor vehicle () equipped with two or more wheels fitted, each, with a tire, driving-related quantities related to driving of the motor vehicle (); computing () second frictional-energy-related quantities related to frictional energy experienced, during driving, by a given tire of the motor vehicle () by providing a predefined vehicle dynamics model that mathematically relates the acquired driving-related quantities to the second frictional-energy-related quantities, and computing the second frictional-energy-related quantities by inputting the acquired driving-related quantities into the predefined vehicle dynamics model; and performing a tread wear estimation () and a remaining tread material prediction () based on the second frictional-energy-related quantities computed and the calibrated tread wear model. The tread wear model calibration step () further includes: performing () tread wear tests on one or more tires; and measuring () tread-wear-related quantities indicative of tread depth reductions resulting from the performed tread wear tests, and first frictional-energy-related quantities related to frictional energy which the tested tire(s) is/are subject to during the performed tread wear tests. Determining () a calibrated tread wear model includes: providing a predefined reference tread wear model that mathematically relates frictional energy experienced by a tire along a driving route to tread wear caused by said frictional energy through given parameters; computing calibration values of the given parameters by inputting the measured tread-wear-related and first frictional-energy-related quantities into the predefined reference tread wear model; and determining the calibrated tread wear model by applying the computed calibration values in the predefined reference tread wear model.",
