A work vehicle includes one or more leanable wheels, in which the lean angle of each leanable wheel is automatically controlled according to one or more external factors. Factors influencing the lean angle of each leanable wheel may include: draft load arising from externally imposed forces, such as forces arising from moving earthen materials with a vehicle-mounted moldboard; the rotational position of such a moldboard with respect to direction of travel; turning radius of the vehicle during a turning maneuver; engine speed and/or transmission gear; and the angle of the vehicle itself with respect to vertical (i.e., whether the vehicle is on sloped ground). A control system may automatically adjust wheel-lean depending on inputs indicative of any combination of the above-mentioned external factors.
