An apparatus for and methods of dismounting and mounting tires onto vehicle wheels without removing the wheels from the vehicle. The apparatus includes driving elements for rotating a tire contacting the same, held in a body and operated by a power source. A pair of tire bead breakers may also be mounted in the body and operated by a power source. Tire cutting knives may be secured in the body for selectively cutting up a tire mounted on a wheel of a vehicle. A tire bead deflector is mounted on a flange of a wheel from which an old tire is to be removed after its beads have been broken, or to which a new tire is to be mounted, and the old tire to be removed or the new tire to be mounted is lowered into contact with the driving elements in the apparatus to enable the driving elements to rotate the old or new tire to either remove the old tire from or mount the new tire on the wheel. The apparatus may be made mobile by adding wheels thereto.
