An apparatus for indicating tire pressure is disclosed which indicates whether the tire pressure in a pair of pneumatic tires is low, normal or excessive. The apparatus includes a valve body which is operatively connected to each of the tires and comprises a valve which longitudinally moves in the apparatus responsive to air pressure. The valve is operatively connected to a scale pan having an arcuate display portion at one end thereof. The display portion on the scale pan includes colored rectangular segments which are visible through a sight window in the apparatus. The scale pan pivots in response to valve movement and the colored segment visible in the sight window indicates whether the tire pressure is low, normal or excessive.
