A system and method is disclosed for controlling at least one traction motor driving an axle on a vehicle. The vehicle includes a plurality of axles on which wheels are mounted. The method may include determining whether at least one of the wheels on at least one of the axles differs in diameter from at least one other wheel on a different one of the axles by more than a threshold value. The method may also include increasing a torque provided by a traction motor driving an axle with at least one wheel that has a larger diameter than at least one other wheel on a different axle.
