If your tires are losing air the issue is most likely caused by your CTIS system failing, SWATMOD makes a delete kit for your MRAP that is extremely easy to install and comes with everything you need. The kit completely disconnects your wheels from the CTIS system. In some cases the CTIS system isn't complete/operable anyways. This eleiminates the problem.
 
The kit includes 4 CTIS delete valves and all necassary hardware, this easily replaces your current CTIS valves on your rims which can be done with an allen wrench and about 20 minutes of time.
