A tire changing system (10) with frame mounted jacks and lug wrench (44) comprising a vehicle having a plurality of wheels (14) and a frame (16) with a pair of longitudinal lower supports horizontally situated on a lower surface thereof adjacent to sides thereof; four housings (20) each having a horizontally oriented upper extent (22), a vertically oriented intermediate extent (24) integrally coupled perpendicularly to an edge of the first horizontally oriented extent, and a horizontally oriented open lower extent (26); four jacks (30) coupled to the upper extent of an associated housing, each signal for raising an associated wheel above the ground and a retracted position upon the receipt of a lower signal for lowering an associated wheel to the ground thus allowing normal operation thereof; and a control mechanism (52) for allowing a user to selectively transmit to the jacks the raise signal and the lower signal.
