Method for estimating the profile depth of vehicle tyres on a vehicle with twin tyres, characterized by the method steps of: a) driving a vehicle over a predetermined driving distance in a driving section, the vehicle comprising at least one axle with at least one set of twin tyres comprising an inner vehicle tyre and an outer vehicle tyre, b) determining a plurality of driving parameters of the vehicle during the journey in the driving section, the plurality of driving parameters comprising at least the lateral acceleration, as well as the following method steps in each case for the inner vehicle tyre and the outer vehicle tyre of the set of twin tyres: c) calculating, on the basis of the determined driving parameters, the forces acting on the vehicle tyre in the driving section and determining an abrasion index, assigned to the driving section and determined according to the method disclosed on page 28, line 10 to page 30, line 14 of the original description, from the calculated forces while taking a plurality of influencing parameters into account, the influencing parameters being selected from the group consisting of vehicle parameters, environmental parameters and tyre parameters, the influencing parameters comprising at least information concerning the tread material of the vehicle tyre and concerning the initial profile depth at the beginning of the driving section, with the position of the respective vehicle tyre in the set of twin tyres being taken into account by a position correction factor, and d) estimating the final profile depth at the end of the driving section for the vehicle tyre on the basis of the respective initial profile depth at the beginning of the driving section while taking the respective abrasion index into account. a) driving a vehicle over a predetermined driving distance in a driving section, the vehicle comprising at least one axle with at least one set of twin tyres comprising an inner vehicle tyre and an outer vehicle tyre, b) determining a plurality of driving parameters of the vehicle during the journey in the driving section, the plurality of driving parameters comprising at least the lateral acceleration, c) calculating, on the basis of the determined driving parameters, the forces acting on the vehicle tyre in the driving section and determining an abrasion index, assigned to the driving section and determined according to the method disclosed on page 28, line 10 to page 30, line 14 of the original description, from the calculated forces while taking a plurality of influencing parameters into account, the influencing parameters being selected from the group consisting of vehicle parameters, environmental parameters and tyre parameters, the influencing parameters comprising at least information concerning the tread material of the vehicle tyre and concerning the initial profile depth at the beginning of the driving section, with the position of the respective vehicle tyre in the set of twin tyres being taken into account by a position correction factor, and d) estimating the final profile depth at the end of the driving section for the vehicle tyre on the basis of the respective initial profile depth at the beginning of the driving section while taking the respective abrasion index into account.
