Pull eight bolts using two 13mm wrenches and remove the front to rear
driveline and you will be fine.  You can also take the tire to someone and
have them replace the stem.  For those in dire situations with a few tools,
a valve stem, and some resourcefulness you can fix it yourself.  It is
possible to break the bead of the tire onsite and replace the valve stem
without removing the tire from the rim provided you have a new stem and
source of air or some starter fluid and a match.  Not for the faint of heart
but can be done.
