An automatic tire mounting system for a vehicle is provided to move a nut runner automatically by employing a triple axis conveying device, align the nut runner about a tire by using an aligning guide, and fastening hut nuts by using a rotation unit. An automatic tire mounting system for a vehicle comprises a nut runner(3), a triple axis conveying device(5), a vehicle sensor(13), an aligning guide(9), and a socket aligning unit. The nut runner includes a plurality of sockets(1) which are installed to fasten a plurality of hub nuts(21) by a predetermined torque. The triple axis conveying device is installed to convey the nut runner along three axes crossing one another in a three dimensional space. The vehicle sensor is attached to the nut runner to detect a vehicle which is conveyed by the triple axis conveying device. The aligning guide is installed to align the nut runner with regard to a tire(7) of the vehicle. The socket aligning unit is installed to align a plurality of sockets with regard to the hub nuts. The vehicle sensor is a photo sensor, which detects whether vertically projected beams are interrupted or not by the vehicle. The align guide includes two linear arms(9) which are attached to the top and the bottom of the nut runner and enter the space in a wheel housing. The socket aligning unit includes a rotation unit(17), and a laser sensor(19). The rotation unit turns the sockets with regard to an outer case(15) of the nut runner integrally. The laser sensor is attached to the rotation unit to detect the location of the hub nut.
