etween your vehicle’s -10 TM and TC 21-305-20,
Manual for the Wheeled
Vehicle Operator,
you can fnd just about everything you need to know about using
tire chains on your vehicle.
The -10 TM is your number one go-to source For tire chain help—unless there’s no
inFormation in it on tire chain usage. That’s when the TC takes over.
Note this inFo:
•± For±M939A1-series±and±M939A2-series±5-ton±trucks,
use chains on the intermediate
axle only. CTIS doesn’t limit the use of chains on the intermediate axle.
•± For±HMMWVs,
Para 3-22 of TM 9-2320-280-10 and WP 0123 of TM 9-2320-387-10 say
that tire chains must be used as an axle set. That means you can use chains on just the
front wheels or just on the rear wheels. You don’t have to use them on all four wheels.
•± For±HEMTTs,
use chains only on both rear axles. On M978 fuel tankers,
never
use chains
when driving on paved surfaces. They could cause sparks, which can lead to a fire.
•± For±palletized±loading±system±(PLS)±trucks,
use chains only on axles No. 3 and No. 4.
Don’t use chains when driving on hard surfaces where there is no wheel slippage.
Chains can cause severe component damage under “no-slip” conditions.
Also, set the CTIS to CROSS COUNTRY and travel no faster than 10 mph (16 km/h)
on-highway or 15 mph (24 km/h) off-highway.

Chains
Tactical Vehicles…
Tire Chain
Placement Made Plain
Remember, also, that it’s
still
important to select
the right transfer range
for driving conditions, as
prescribed in your -10 TM.
Now I know
the
right
way
to use my
HEMTT’s tire
chains!
Good!
just make sure
you’re clear on how to
correctly place tire chains
on the
other
tactical
vehicles in your unit, too.
