If the vehicle is heavily loaded, check the tire pressures and correct them if necessary.
When parking your vehicle, make sure that the tires do not get deformed by the curb or other obstacles. If it is necessary to drive over curbs, speed humps or similar elevations, try to do so slowly and at an obtuse angle.
Otherwise, the tires, particularly the sidewalls, may be damaged.
