A tire pressure gauge (100) with a valve cap wrench is disclosed. A bore (135) at one end (120) of the tire pressure gauge may be used to grip and remove a valve cap mounted on a valve stem of a tire. A port (125) at the other end (105) of the tire pressure gauge may be used to measure air pressure in a tire. The measured air pressure may be displayed on a display (125) on the pencil gauge. The cap wrench may have a collet to hold a valve cap and a switch to tighten and loosen grip on a valve cap. The cap wrench may also have a plunger to push a valve cap out of the pencil gauge.
