Method for inflating dual pneumatic tires

The method of adding pressured air to dual pneumatic tires wherein both tires have valve stems through which air is added and on which is threaded a mud cap, the method comprising the steps of:

• providing an elongated first tool having an end forming a cavity for fitting over and grasping the mud cap;
• placing the elongated first tool in position over said mud cap and twisting the first tool to screw said mud cap off of said stem;
• removing the first tool and mud cap from said pneumatic tire;
• providing a second elongated tool comprising a hollow tube having a first end forming an air intake and a second end forming a cavity for fitting over said valve stem and having gripping means released by pushing on said air intake while pulling on said hollow tube;
• placing said second elongated tool second end over said valve stem while pushing on said air intake and pulling on said hollow tube and then releasing said hollow tube to allow said gripping means to grip said valve stem and hold said second tool in place;
• placing a source of air in contact with said air intake to supply air to said pneumatic tire, and then removing said air source;
• pushing on said air intake while pulling on said hollow tube to release said gripping means;
• removing said second tool from said valve stem;
• replacing said mud cap with said first tool and screwing said mud cap on said valve stem;
• and
• removing said first tool from said mud cap.
