Combat Vehicles…
Weather Cracking
All vehicles:
If weather cracks
extend completely across the tread
surface or are more than
1
∕
4
inch deep,
the roadwheel should be replaced.
Chunking
M1-series tanks, M2/M3-series
Bradleys, MLRS, M88A1 recovery
vehicle and M60 AVLB:
Look for
large chunks of missing rubber that
both measure 3x4 inches or more
and
expose
metal on the roadwheel.
Also, if the total area of smaller chunks
exceeds 20 percent of the tread surface,
even with
no
metal showing, replace the
roadwheel.
M113-series FOV, M551 Sheridan,
M992A2 ammo carrier, and M109-series
SP howitzers:
Chunking that covers
half the width or more
of the roadwheel and
exposes metal means
the roadwheel should be
replaced. Smaller chunks
whose total area exceeds
20 percent of the tread
surface, require a new
roadwheel, too.
Weather crack deeper
than 1/4 inch?
Look for chunking
that exposes metal
Man! I’m
glad to
finally
get
some new
roadwheels!
Yeah!
Those old
ones were
worn
out!

Well, you
could
search
through your vehicle TMs and TM
9-2530-200-24,
Standards for
Inspection and
Classification of Tracks,
Track Components and
Solid-Rubber Tires.
Or you
could
just keep
reading.
..
So the rubber
on your combat
vehicle road-
wheels looks
a bit
worn.
Question is,
how
worn must
it be before you
replace
the
roadwheel?
