Abstract:
1. A method for fitting tires to driving axles of a vehicle carrying heavy loads on one of type A route where the vehicle ascends under load with a driving torque and descends empty with braking torque and type V route where the vehicle ascends empty and descends under load with a braking torque, said method comprising: choosing tires for said vehicle, these tires having a tread of a maximum width L and an outer surface forming a rolling surface the tread comprising: determining a type A route or a type V route to be taken by said vehicle; when the route is of type A, fining the tires to the driving axles such that for each of the first transverse grooves in the edge portions of the tread, one of the rubber faces has a smaller angle of inclination and comes into ground contact before the other one of the rubber faces does; and when the route is of type V, fitting the tires to the driving axles such that for each of the first transverse grooves in the edge portions of the tread, one of the rubber faces has a larger angle of inclination and comes into ground contact before the other one of the rubber faces does.
