Correct Lug Nut Torque

[Rifleman]

I have a M925A0 and i need to rotate my tires so i was looking in my tech manual 9-2320-272-20-2 dated 10-1985 and it list the lug nut torque as 450 to 500 foot pounds for the M925A0 and A1.

Now for the problem, i crossed checked the lug nut torque against the latest tech manuals and came across a conflict. The new tech manual 9-2320-272-23-3 dated 9-2012 list the torque at 325 to 350 foot pounds for the M925A0 and 450 to 500 foot pounds for the M925A1 and A2.

So my question is this, which tech manual do i go by, do i torque my lug nuts to 450 foot pounds per the old manual, or do i torque them to 350 foot pounds per the new manual?

Just a little more info, my truck has the G177 11X20 Goodyear tires not the old NDCC tires or the newer Super Singles.

How about average - (325+500)/2=412.5

Good question, recently someone had a good writeup on something then noted the torque for the lugnuts at 325-350, I noted the manual I looked at -24 when torqing my A2 wrecker saying 450-500 and they came up with yet another at 400-450 or thereabouts...... I'd like to know which TM is correct too.

Since you're still on skinny duals, use 325 to 350. The 450 to 500 is for the SS's (which are a bit heavier)

Hey looks like the -23 supercedes -24...... Wierd, I just assumed the -24 was later than the -23! Looks like I'm over torqued!!!! And that guy was correct all along.

From the -23 TM:
*SUPERSEDURE NOTICE - This manual supersedes TM 9-2320-272-24-1, TM 9-2320-272-24-2, TM 9-2320-272-24-3, TM 9-2320-272-24-4
and TO 36A12-1C-1155-2-1, TO 36A12-1C-1155-2-2, TO 36A12-1C-1155-2-3, & TO 36A12-1C-1155-2-4, dated 30 June 1998,

-23 is 450-500 for the A1/A2 rims, looks like I'm okay.
