Abstract
A pneumatic circuit whereby small amounts of variations in pneumatic pressure in a tire occurring during tire testing can be adjusted in a short time. The pneumatic circuit includes an air supply source which generates compressed air to be supplied to a tire retained in a tire testing device; a pressure regulating valve which regulates the pressure of the compressed air generated; a discharge/supply valve provided downstream of the pressure regulating valve and by which compressed air is supplied to, or discharged from, the tire; a pressure detection unit provided downstream of the discharge/supply valve and which detects the tire pressure inside the tire; and a volume adjustment mechanism provided between the pressure regulating valve and the tire and which increases or decreases the volume of compressed air in an airflow path between the tire and the pressure regulating valve, as well as in the tire.
