PROBLEM TO BE SOLVED: To predict wear of a tire precisely. SOLUTION: This method for predicting tire wear includes an on-bench wear energy measurement process, weighting factor determination process, total wear energy estimation process, and wear prediction process. In the on- bench wear energy measurement process, wear energy e1 of a tire in a steady state, e2 in a turning state, e3 in an acceleration state and e4 in a deceleration state are measured by an apparatus for measuring on-bench wear energy. In the weighting factor determination process, weighting factor (a) in a steady state, (b) in a turning state, (c) in an acceleration state and (d) in a deceleration state are determined based on the frequency of each running state of an actual vehicle: steady, turning, acceleration and deceleration. In the total wear energy estimation process, total wear energy Et of the tire generated from running of the actual vehicle is estimated by multiplying each wear energy e1 to e4 by the respective weighting factor (a) to (d) and adding them up. In the wear prediction process, tire wear is predicted based on this total wear energy.
