Stryker…
Mileage Limit
on TOWs?
Dear Sergeant A.B.,
No, it isn’t. The Army tested TOWs after
2,000 miles of vibration and found the
missiles still passed all tests. So you don’t
need to track mileage on
your TOWs.

Stryker…
Raise the Pressure
D
rivers, the highest air pressure setting for your Stryker’s CTIS system is 80-85
psi. That’s just not high enough for vehicles equipped with slat armor in Iraq. You’ll
run through tires quicker than a NASCAR driver at those lower pressures.
The optimum air pressure for Stryker tires in Iraq is 95 psi. So how do you get it
that high?
First, disengage the CTIS system by
flipping the switch on the driver’s panel.
If you leave the system on, it’ll automati-
cally lower the pressure back to 80-85
psi, no matter how much air you add.
Dear Half-Mast,
We’ve been told to keep track of
how many miles our Strykers travel
with TOW missiles loaded. The rea-
son is supposed to be that after
TOWs have bumped along for 2,000
miles they need to be turned in
because that much vibration affects
their gyros. Is this valid?
SGT A.B.
looks like
your tows have
2,000 miles on
them. time to
change ‘em out.
no need
to do that.
there’s
no
mileage limit
on tows.
my tires
can’t take
this abuse!
they need
more
air pressure!
The third option is ordering a
50-ft hose assembly, NSN 4720-01-
166-1087, and a pipe coupling, NSN
4730-00-223-9255, to extend your
BII air hose. Here’s how:
1.
Unscrew the quick-disconnect fit-
ting from the end of the gauge
assembly.
2.
Screw one end of the hose exten-
sion into the gauge assembly.
3.
Screw the pipe coupling onto the
other end of the hose extension.
4.
Screw the quick-disconnect into
the other end of the pipe coupling
and hook it to the Stryker’s air outlet.
Next, manually inflate the tires to
95 psi using the air hose and inflation
system that comes equipped on each
vehicle.
Disengage CTIS system
by flipping switch down
Manually air each tire to 95 psi
If you haven’t noticed already, the 6-ft air hose, NSN 4910-21-920-4694, that
comes in your Stryker’s BII doesn’t reach very far. That leaves you with only a few
options. You can pull another Stryker up next to each of your tires and air up from
that vehicle or you can local purchase a longer, 25-ft hose.
Make sure
you check the
tires often
to keep the
air pressure
at 95 psI.
