After Pearl Harbor happened December 7, 1941 America rallied for war. In January of 1942, to help with the war effort, the government passed the Emergency Price Control Act. Under this act the Office of Price Administration (OPA) gained the authority to regulate and set prices for goods. The OPA also started a rationing program to try and keep inflation down and make a fair distribution of goods during the war effort. Denver’s contribution to the program was tire rationing. Denver was divided into six districts and the board of the districts had control over tire and tube sales. Colorado’s tire rationing was essential for preserving rubber, especially since the Japanese had halted some of the rubber imports. If a driver needed to get a tire replaced the garage that they went to would give them a certificate, the driver would then take that certificate to the board of their district and the board would look at the government’s list on who gets tires and would then make the decision if the driver gets a tire or not. This tire rationing was very important for America as seen in a letter to the boards from the Secretary of State, Walter P. Morrison, states that, “"You have been honored by your country and your state with a call to a service which in many ways is more important than carrying a gun. You are called upon to act in a capacity which calls for intelligence, patriotism and unselfishness.… Unless a job is done right, the United States will be crippled in its efforts to achieve a victory in this war.” With the anniversary of Pearl Harbor it goes to show that everyone contributed to the war effort.  Little things like a single city rationing tires greatly affected the outcome of the war, even if it didn’t really end up in the textbooks.
