A tire gauge is a handy automotive tool - for car owners and auto mechanics alike - in the same way that an air compressor or jump starter is. There's a few different varieties available - some are better for sitting in the trunk or home garage for car owners, others better suited to commercial auto workshops.
Used for measuring the air found within pneumatic tires, they work by detecting the level of PSI - pounds per square inch - which in turn allows the user to determine that the tires are safely inflated, so avoiding the possibility of over or under inflation.
