A system for a tire caddy and jack device to help a user easily perform tire changes on various-sized vehicles is disclosed. The Tire Caddy Jack is built using a base box supported by a plurality of casters that permits the entire Tire Caddy Jack to be moved easily around an automobile repair facility or garage. A scissor lift assembly is mounted in the center of the top surface of the base box. A scissor lift crank attaches to the scissor lift assembly that when turned will cause the scissor lift assembly to extend upwards, raising the tire and wheel above the ground. The tire and wheel rest upon rollers that are coupled to a pair of twin half roller arms mounted on top of the scissor lift assembly, permitting the tire and wheel to smoothly be raised and lowered to mount and unmount the tire and wheel onto a vehicle. The Tire Caddy Jack supports the tire and wheel while the mechanic removes or replaces the lug nuts or lug bolts that hold the tire and wheel on the vehicle.
