TM 5-3805-260-24 Current Recommendation Use nitrogen (N2) gas for all pneumatic tires.  Nitrogen not burn inside the tire. WARNING Correct  nitrogen  inflation  (charging)  equipment  and training  in  its  use  are  needed  to  prevent  too  much pressure  in  a  tire.    A  tire  blowout  or  rim  failure  can result  from  equipment  that  is  not  correct  or  is  not correctly used. Also,    the  use  of  nitrogen  instead  of  air  in  the tires,  decreases the amount of tire deterioration.  This is especially important for tires that ha-e an expected long service  life  (4  or  more  years).    It  also  decreases  the corrosion of rim components, which decreases disassembly problems. The pressure of a full) charged nitrogen cylinder is   approximatelI5   15000   kPa   (2200   psi).      This   high pressure  can  cause  a  tire  blovwout  and  or  rim  failure  if the  charging  equipment  is  not  used  correctly.    See  Tire Inflation (Charging) With Nitrogen. Tire Inflation (Charging) With Nitrogen WARNING Servicing    and    changing    tires    and    rims    can    be dangerous.  This work must be done only by trained personnel   with   correct   tools   and   procedures.      If correct  procedures  are  not  followed  while  servicing tires   and   rims,      the   assemblies   can   burst   with explosive force and cause serious physical injury or death.      Follow   carefully   the   specific   information provided by your tire servicing man or dealer. When tires are changed be sure to clean all rim parts.    If  necessary,    paint  the  components  to  present corrosion.  Sand blasting is recommended for removal of rust.    Check  all  components  carefully  and  replace  any cracked,bad)    worn,        damaged,    severely    rusted    or corroded parts with new parts of the same size and type.  If there is any doubt, replace  with  new  parts.    Never  rework,    weld,    heat  or braze any) rim components. The     tires     on     these     machines     are     inflated (charged) with nitrogen instead of air. The recommendation  is  that  nitrogen  be  used  for  pressure adjustments in a tire.  See your tire dealer for the correct tire pressures for job conditions and for an) questions on nitrogen inflation. CORRECT POSITION FOR TIRE INFLATION (Behind the Tread) WARNING A tire blowout or rim failure can occur during tire inflation. To prevent possible injury get next to (behind) the tread, as shown,  when inflating a tire. Set the regulator of the nitrogen inflation equipment at no more    than    140    kPa    (20    psi)    over    the    correct    tire pressure. CAUTION Use only the 6V4040 Nitrogen Tire Inflation Group to  inflate  tires  from  a  nitrogen  gas  cylinder.    See Special Instruction,  Form Number SMHS7867 for tire inflation instructions. Use the same tire pressures for nitrogen inflation that are used for air inflation.  See the Operator’s Manual for the shipping and operating pressures. 2-156
