Paul,
   I hope your automotive tire pump has a supply of Nitrogen, we're told that the Oxygen in air could detonate in the oleo.  Also, be sure that the Schraeder Valve is the high pressure type, the stem is slightly shorter and usually grey in color.   The normal red valve will bleed off and not trap pressure in the oleo....
