SWITCH ON tIRE SWITcHInG
HoldÜ it! You don±t rotatE tires on
your M880 or other TM´266´series
Ý
µÞ/´ton truck like you do on your
mißitary´design àrucks·
This truck±s got radial tiresá
tubeless stâel belted radials-so you
never cãange ±em from one side of
your truck to the other· Instead, you
switch ±em only on the same sideá
front tire to the rear and rear tire to
the front· äee tåe poop in TM 9´2320´
266´20 ¶an 76), page 2´62, para 2´
76a(2) and æig 2´71·
The TM shows ç different ways of
rotating tires-the 4´wheel pattern
and the 5´wheel· But, like the TM says,
it±s best to stick to the 4´wheel setup·
And you never mix radial tires wèth
bias´ply tiresésee êWarning,ë para µ´
ìf, page 1´5, TM 9´2320´266´10 ¶an
76)· You can tell a radial by the êÅë on
the tire·
That ê65 PäI±± on your M880±s tires
is not your operating pressure· That±s
top pressure-maximum·
Tire pressure for your truck is 35
PäI front and 5 5 PäI for the rear and
spare·
