ABSTRACT:
A tire pressure gauge includes as in the prior art a cylindrical housing securing thereto a tubular member securing thereto a first measuring head, a piston rod, a spiral spring, a sectorial plate capable of being pivoted by the rod, a pinion meshing with the plate, a scale plate, and a needle connected to the pinion wherein the improvement is that the gauge further includes a soft tube having a first end detachably connected to the first measuring head and a second end connected to a second measuring head. Such gauge can conveniently measure the air pressure of inner wheels of a truck or a bus with the second measuring head without the need of bringing the cylindrical housing into the bottom of the bus.
